I wouldn't because I have kids.
But if I didn't, then here's what I'm thinking:
If this person was my friend, such a good friend that I'd consider dying for, then that would mean I love him/her unconditionally (if there's such a thing) and I'd have to ask myself, "Self," I'd say, "if I died for him/her then they'd miss me and they'd be in more pain then if I didn't die for them and let them die instead. So which pain is greater? That of missing the dead or actually being dead and there'd be *no* pain *in* death"?
*sigh*
Oh the thinks I have thunk....Dr. Suess, take me home....
