There's a girl I know who did something terrible once. She had been abused and mistreated, and so she killed many humans. She declared war, and to stop her from killing everyone we had to seal her away.

But sealing her away didn't fix anything. Hundreds of years later, it all started again. But this time... we spoke to her and tried to understand her. And this time she was able to live in peace along with everyone else.

Later, that girl... she did good things. She did great things. That girl helped regenerate our world.

So, I would say. Your duty is to be like that girl. Despite her guilt and her anger she moved on and did things that helped everyone.
