I'd save you, wouldn't care if I died, because I'd already be dead before I could care. I'd rather save someone else with more of an opportunity to actually do something instead of letting myself live and have myself do absolutely nothing useful. I'd spend the rest of my life hating myself anyways.
I'd do it if it keeps others alive, and if whatever sacrifice I may or may not be making can still help someone enjoy their life. It'd be better for them.
...I guess i'll save you, you fucking amazing ninja.
