So it's gonna sound wierd but, maybe she heard stories that the monsters are mean guys right? So she is trying to kill them cause of the stories. Yes, monsters were trapped in the Underground before Chara was born, but it was a long, long time before Chara was born. Presumably monsters aren't even remembered on the Surface. The only knowledge that anyone has is that those who climb Mt. Ebott never return.

And since the entire war was started by the humans because they feared monsters might absorb their souls, and the war was completely lopsided (not a single human life was taken, monsters all being too weak on their own), I highly doubt that there are stories told of monsters (that is, the actual monster race living in the Underground) making them out to be villainous.
