Ehhhh, that's not all true...In the game, Chara is seen as the demon of the underground, when that's not all true. It turns out YOU the player are the bad guy. Think about it, you do the pacifist route and then you reset because you want to try the genocide route (or normal). Sure Frisk is their own character but I think I made a long enough point. But as a side note this picture is cute!
