Undyne:You were the one and ONLY thing between monsters and FREEDOM!! What, do you want me to just not free an ENTIRE KINGDOM? What is WRONG with you?!

Hypothetical responses from Undyne aside, her reasons for killing humans are to get monsters on the Surface. I don't know where she got the idea that moving from the underground to the Surface was worth killing innocents from, though. I'm with Toriel on this one-It's just not worth it. (I don't know if she approves of the rumoured plan beyond that, about killing humanity afterwards.. If she's on board with that, then she's CLEARLY a hypocrite. I really hope her supposed care for humans in the introduction to the Undying battle, from the line "This isn't just about monsters anymore, is it?", is genuine.) So, to both of you.. That's her motivation-Freeing monsterkind. So, take that into account when forming your next argument for or against her. Now that we have that down, we should do far better in actually figuring out whether or not her actions are unjustified.
