Cute!

I personally can't call him bad for eating humans. He's such a simple-minded animalistic guy. He might have done something that goes against our sense of morals, but I feel he can't be evaluated to this standard since he's pretty much amoral, not immoral.
To me, it'd feel like calling a cat bad just for chasing a bird or trying to eat it. It's part of its instincts. It's not morally right but doesn't make a bad cat, since cats are hardly concerned about morals(as other animals).

Does it make sense?

Ya yer right even in his human form he’s like a child too
