You'd become a dick, too, if your being was corrupted by a blood-thirsty human 030

cant argue with that tbh

Chara or Frisk?

Is it wrong that genocide run made me feel bad for Flowey?

well technically speaking, and to anyone reading this, spoilers, flowey is asriel with no "soul" and he has stated that because of the absence of one, he cannot "feel". but i think his state of being is like the kh nobody rule where he's really not without a "soul" because he is still capable of some feeling, but because his "soul" is fragmented, these feelings aren't properly mapped accoirding to his original state of living until he receives a proper monster soul.

There's also how Chara's being might be tied to him as well. Chara seems, pretty messed up.
