@Freddy Fanatic:The only reason why Frisk is a blank slate is because you control them. They're supposed to be YOUR player character. You don't control Chara, though you can name them..

@Rafip:Chara punishes Frisk by forcing them to literally give up their SOUL. But to say it's just to punish Frisk doesn't work. There just isn't a good reason for this, since killing everyone actually leads Chara to thank you and call you a true partner. Perhaps they showed up to kill everyone? They want our soul because they know with it, they can possess us? In that case, it's like selling your soul to the devil. This would also explain why they encouraged a pacifist route after the second genocide run, as they want to kill everyone on the surface too.

Remember, we're never given the choice to move onto the next world like Chara said.. Instead they play dumb and assume Frisk wants their own world back.
