Well in the beginning I loved Micchy so much. He was so innocent and a cool character but ever since he joined Yggsdrail and did that to his OWN brother, also shooting Kouta from behind when he was about to henshin. And started backstabbing, that just pushed me to hating him. And now I hate him even more than before. But I still want to not hate his character so much. I want old Micchy back so bad.

I never hated him to begin with, he simply was a misguided character that took a lot of bad choices.

And the events in the episode are consistent with it.
He earned this path.
