Here is the bad

I cant see it is all White for chara

Chara isn't evil. they're neutral.

If anything, Chara is good.
They sacrificed their life to try and save monsterkind. That gets you pretty high in the good books.

Did I make a mistake playing gdniside before pasifist

yes.

genocide is the best route, so no.

no its not

nope, it is.

how?

first of all, everyone dies
second of all, you hear them cry for mercy as you brutally end their lives.

Trust me, you wanna rethink this meme. I speak from experience.

Chara isn't evil, the player is evil.

you forgot to add the key words "can be"

(At least in the genocide path)

yes
