Easily Pennywise, Champ is more hateful but Pennywise mind rapes, tortures and eats children and adults on a daily basis.

Champ is an awful scumbad, but It has done so much worse.

Haven't watched Akame Ga Kill! (and I don't intend to because it sounds extremely dumb and edgy like a lot of other anime) but Champ sounds morally worse to me.

Pennywise needs to eat humans in order to survive and it tortures its food to make it tastier. It is not very clear to what extent its actions are caused by its nature and it is possible that it has moral agency issues because its backstory is never explored.

Champ has a lot less resources than Pennywise, his actions are not caused by his nature and he doesn't need to rape and kill children to survive, so I choose him.

You could say that with almost any PE vs Pennywise though, it's not in their nature to do it but Pennywise is so cruelly sadistic in his actions.

@Romeo and Robot

You are right and this is why I also take into consideration the crimes they commit and other potentially mitigating factors.

For example, I don't think Percival C. McLeach is worse than Pennywise because all he tries to do is kill one kid gruesomely.

People are contemplating cutting him from PE. Nothing indicates he knew the animals were sapient.

@Romeo and Robot

Yeah, I was wondering about him too. The only argument I could see for keeping him is that he tried to feed the main kid protagonist to a bunch of crocodiles which might be enough to pass the baseline but I am not sure.

Also, about Champ, another reason why I choose him is because he is a normal guy and he doesn't have Pennywise's powers and I am pretty sure if he had them, he would be just as bad if not even worse.
