For that to happen, Revice would need a lovable character. :p Well, I guess there's Yukimi, my attachment bias would definitely make me a lot more mad about her death than anything for Chigusa or Yosuke. Of course, I'd also be pretty mad at Michinaga if Sara had become a victim of Heaven and Hell.

We should still consider the difference in motivation though, to determine who has more sympathetic qualities. While not inherently redeeming, this information can be used as a catalyst for redemption. Like Zea did for Gai, which gave him the opportunity to use his genius and wealth to atone for his past.

Olteca seeks validation for his genius. You claim his murder of Yosuke was to spite Tamaki, but I think it's more like he did it for the attention. Due to his father's abuse and induction in to Deadmans, he only knows how to get that by making his friends hate him. He's a tsundere villain, but as his toxic behavior is never addressed, he's denied any catalyst for redemption.

Daichi seeks the memories of all humanity. As his desire is too big to be granted by living honestly, he's willing to use any means necessary. The problem here is that characters have already given him a generous amount of chances to redeem himself and he keeps betraying and exploiting their trust. His plans are overly logical and thus they fail when someone inevitably makes an emotional choice.

If Olteca and Daichi swapped shows, I think the outcomes would be very different.

Those people seem to miss the point of Kekera by claiming they're like him. The sponsors are supposed to represent sides of the audience. Everybody's a little bit like Kekera in the sense that we need to see our characters suffer so they can grow from it. But most people aren't extreme enough that they'd orchestrate that suffering directly, or want them to suffer constantly. Kekera's vision of an ideal Kamen Rider seems to be stuck in the Showa Era, but beyond what even Ishinomori would force on a hero. You're right that proving Kekera wrong will be complicated. Even if he dies by Tycoon's blade, he may die laughing proudly at the Kamen Rider he made. How can such a person be punished?

Regarding the part about demonizing Keiwa, well, stay tuned for my thoughts on Episode 42. This is only the tip of the spear.

Michinaga doesn't have reality warping powers like Geats IX though and even with those powers, Ace can't do it with his Kirakira alone. If the Jyamafied people can't be turned back, right now, then Michinaga has to choose in the moment between letting them rampage on the gamble that they can be saved later, or destroy them to prevent further deaths. Maybe it's the wrong choice, but to have the power to protect people and neglect to use it would feel irresponsible to him. It's a burden every Rider has to endure, the reality that fighting will cause victims in some scenarios, but it's better than not doing anything at all.

I agree that Beroba isn't the worst, even though she's still a pretty terrible person. The future definitely has a serious cultural problem that allows these toxic behaviors to exist, as I doubt Beroba ever had anybody to teach her that making people suffer for entertainment is bad when this is exactly what the DGP did since obtaining Mitsume. Personally, I would give the acolade of worst villain to Daichi, as he's part of our contemporary moral culture and yet he still turned out like an unscrupulous traitor and serial killer.

Well no, obviously I don't meant for them to get Daichi redeemed or such (and I'd hope he gets what's coming to him and not a slap in the wrist outcome, and I'm worried about Kousei in the next episode). Though perhaps to control his behavior for others' benefit, it can be done in pragmatic villainy way (doing good/not doing bad out of their best interests, not due to standards). Or keeping him alive in leash to examine his lab to get more knowledge regarding it. What I'm thinking was that, they perhaps should look for a way to extract Daichi's intelligence or such (... like the opposite of what's Daichi doing of gaining others' memories) and use that knowledge to try creating something to cure them, taking over Daichi's lab too for speed.

Guess I have to back off a bit, and I gotta straighten things up a bit as I do forgot something regarding this, my evaluation of Beroba being the worst was a bit outdated. I thought of this before Suel came to scene. So to update that, Beroba now can be challenged for the worst person in Geats, though I still think she's a candidate, I think it'd be between Beroba, Suel (yeah he can be worse than Beroba, but I don't think it's fully certain yet), or Daichi like you said (though also again, his crimes escalating is a recent stuff). For future stuff, for sure there's definitely terrible eggs from that, but I don't think that I would deem all the future people as inherently terrible yet (maybe can still be similar like humanity in any era), because I've seen similar argument done to humans in out contemporary moral culture, but I feel those are nostalgia bias (usual present time hate stuff) - like in the past there's also "making people suffer for entertainment" stuff too, like decapacitating disliked person in gulliotine for everyone to watch.

I feel that it's not like Taira stopped his business when fighting in the DGP, he can ofc try to do both at once, counting on whatever that will work for him to cure the sick boy on time, though depends on his time management. Probably if Taira has collected enough money, he can retire mid game, which fortunately the DGP isn't like Rider War (where Sano suffered of this) of how there's a chance to forfeit, though with the DGP's consent (Hiroki in PunkJack special).

And there's also those who admit being Kekera, and want for Sara to die, because she's uninteresting (she didn't have much screentime before Hakubi) and if she dies there'd be one less boring characters in the show. But this is the reason why murder is a severe (but not the only one) crime, it can be a huge loss for anyone even if you don't feel the same, and really it shouldn't be taken lightly even in a fiction where it's rife of it; numerous villains who get slap in the wrist outcome due to "redemption". Regarding not that extreme of orchestrating, still dunno if they can't act on it (like not having power/position/etc.) or won't act on it.

I also think, some authority figures in places like school (who is considered right and know the best) are also like Kekera, they want to prolong the suffering of like, students, so that they can "grow", and deem those who break or object as mentally weak, especially done by the opinions of the outside who victim-blames, and I'm afraid that anytime, they can kickstart the idea that lets students suffer constantly so that they can further grow.

Being attention seeking won't put him better on moral standings either way, though you may be explaining this to talk about his writing. I feel that attention seeking can be something of an ego or narcissist incarnate, and also can be limitless like knowledge (that Daichi seeks), it also can not stop overnight after Tamaki gives said "attention", he may want the attention to be certain way to further commit crimes for that. So you do think of Daichi's further appearences as being given a chance to redeem, but for this one you aren't holding those people (instead of Daichi) accountable where they have something as bad that makes them fail to redeem Daichi, unlike for example Gaim.

Eh Ace for now also doesn't find a solution yet for the infected, so the reality warping power argument doesn't apply here. Though perhaps still, even if the reality power argument can solve thing, it's how someone should cooperate with others to get the best outcome, including simple thing such as calling him over monster appearences (like Keitaro or Zack) while he can help neutralizing the monsters but not killing for Geats to do his work, of which it'd be Michinaga's own problem where being a lone wolf, and adamant about doing things his way and his way only, is something completely in his control.

Yes, I personally think that on Tycoon and Buffa, the stock of redemption for this show is complete. There was just too little time left for it not to seem like Ace was suddenly possessed by the all-forgiving Gentaro. If Daichi and Kossei, as well as Kekeru and Beroba, wanted to be redeemed, it would have been done in the thirtieth episodes. At most, Kossey will do a good deed and ask for forgiveness from Neon before a heroic death. And others have a chance to escape into the future and return in a summer movie or crossover.

You are simply looking at the situation from an idealistic point of view. Let's listen to Niram and try to think "realistically!". More precisely, materialistically. Kekera is doing evil, so Kekera needs to be stopped. Kekera's joy doesn't matter, as long as he doesn't hurt anyone.
In fact, it's ideal if Tycoon and Buffa crush each other's supporters. Then Kekera and Beroba will be defeated without getting what they want. But this is unlikely to help Keiwa and Michinaga reconcile, because for this they need to admit their own wrong, and they denied the slightest possibility of it throughout the show. Geats fulfilled his dream in front of their eyes without compromise, and these two simply do not have examples of a different way.
