I believe them to be a misguided, spiteful child, who believes they could kill 2 birds with one stone with Asriel.

I also believes that their views on humanity, along with the value of life itself, depends on the action of Frisk at the end of the game (or the Player, if you’re going the meta route).

So to me, they’re neutral at default, Good at True Pacifist, and Evil at Genocide and afterwards.
