It might be possible. That would explain why he kills for fun, but it’s not an excuse killing innocent children.

He's mentally ill ig

Nah, I got bullied as a kid too, and yet I never become a child murderer like he did

I don't think he got bullied.

That's it, he's just mentally ill without any physiologist help

I prefer to think that there is no why
