My closest friend is my wife. If I die then she has to go on without me, which would be very hard and sad for her, which is why I would chose to have her die over me.

Yea... tell your wife that.

"Hey honey, if it was up to me, I'd let you die to spare my life. You see, it's so you don't feel bad... where you going?" :P

This is why it's important to have a mistress on the side that can substitute for her in this case. That way you can tell your wife that it's for her own protection, and she will appreciate the effort you're going to to keep her safe.

This is morbid.

Kill one person to save 20, or kill 20 to save one? That's wrong.

What if i have two very close friends? I certainly don't like this.

I only have one really close friend. dun dun dun!

What if your closest friend isn't who you think it is?
