Justice or Vengeance (Undertale)

Undyne had always hated humans. They'd trapped her people and left them for dead, only to destroy their beacon of hope as soon as they'd discovered it. Humans attacked what they didn't understand. Humans didn't need love, hope or compassion to exist. Humans were an enemy to be defeated. That was final.

It didn't matter how many times Undyne had seen her dad standing in the barrier room, staring at the four harvested souls with an unreadable expression.

It didn't matter how suffocating the rooms of the palace felt, laden with the fading traces of a queen who'd fled her people so many years ago.

It didn't matter how hollow Gerson's laugh sounded when he heard a younger Undyne ranting about how she'd "give those fleshbag punks what they deserved."

...

It didn't matter how much her soul ached after every nightmare, more than her broken eye ever could.

...

That human had wanted justice, but it had turned into something so much worse.

Could Undyne really believe she was any different?
