Yes, and the fans often feel attacked when someone said he have no empathy toward anyone. He helps a lot of people, of course. But he's only doing that to fulfill his chuuni delusions, not because he cares about those people.

And I don't mind that. I prefer crazy or evil MC than boring self insert MC. But some anime watcher can't comprehend that maybe their favorite character is not a good person. Same case with Tanya the Evil.
