im a fictionkin of 2p england (hetalia) & he sort of kills people and engages in cannibalism sometimes when hes really angry? & i dont even feel that bad about it. i think id actually do it again in this life if i got very mad. is this bad?

I can state unequivocally, absolutely, yes. The urge to murder is always bad no matter what the source is- if you think that you’re going to go through with it. I am not telling you not to embrace the acts of your past if that is what you wish, but by no means do I advise you to replicate them here. If you feel like you are unable to control yourself, I recommend that you look into anger management techniques.
