I wish I could honestly say yes but I'm way too selfish. I guess I can't answer this question unless I was put in a situation where I had to risk my life for somebody I loved.
I love my family, friends, so many people. I'm not some loner who loves nobody but this is my own life at stake. I could die and lose everything, I'm young and there's so much I haven't experienced. On the other hand, if somebody died and I had the opportunity to save them, I would live the rest of my life regretting that.
TL;DR I would like to say yes, but I can't answer for sure unless I was put in that situation.
Would depend on the situation really. If there's a chance to save the person then I'd definetly do it. Some ppl might back out when it gets to the point, but I know I'd rather risk it than having to live the rest of your life with the thought you could have saved someone
