Oh Eiji and Fuwa sounds really good!

Something I always found brilliant about OOO is that it doesn't take the position that desire is bad and people should have as little of it as possible. The Greeed are manifestations of desire running rampant, but Eiji and Dr. Maki are examples of the dangers of not having any desire. So instead of desire being a bad thing to get rid of or a good thing to have as much of as you can, it's all about having a healthy amount of it and expressing it in a productive way.

And what you said about Fuwa made me realize his arc is very similar about anger: Yes, too much of it is a problem, but the solution wasn't to get rid of all of his anger, it was to focus his rage on the evil that actually deserves it instead of letting it spill out against innocents.

And on top of that, Eiji and Fuwa are approaching their dangerous-but-still-needed emotions from opposite directions: Eiji doesn't have enough desire and needs to gain enough to sustain himself, while Fuwa has too much anger and needs to get it under control.

Heck, call it hatred instead of anger and it even makes a good thematic opposite to desire.
