I am not a noble person, nor am I extremely brave. I am a coward, and for me, I am the most important person in my life. So no, I won't sacrifice myself for them.
I'm not one to put my life on the line for people, no matter how much I may like them. The only person I'd probably sacrifice my life for is Nico, but I wouldn't because he'd end up in Hades' palace anyway.
