Funny... Haven't found myself on this site in forever and the first thread I look at is 37 pages long (and as usual, I'm late again, but putting my two cents in anyway)...
I can, without any doubt, say that I would stay. Any buddy, any time. That being said, I don't believe the question (or any situation) is black and white. I believe it's how we perceive the question. The thread title is "What if" and while I have pondered this quite a bit over the past 37 pages, I keep coming back to that question. What if? I don't cave dive, but I am a very accomplished wreck diver (so please base my opinion on this train of thought). Although I understand that the simple act of hope can be a dangerous direction to go in, it's something that is simply a part of me. My 16 year old son was still-born with many congenital heart defects. At that time, we were told that he would not live and if he did he would be a vegetable. We were told this again at 1 year, 3 years, 5, etc. etc. etc. I didn't accept that and I didn't give up hope. Today I gave him another lesson driving my standard shift (it's paid off - grin). 13 years ago, I was told by a doctor to make up my will and get things in order. I have been in and out of remission 3 times, and two months ago, they discovered masses in my lungs. I've never given up hope. Maybe it's these circumstances that would make it easy to risk (or give) my life for another. I have had the opportunity to look back and know that I have lived a very good 38 years. Am I ready to go? Nope, but I don't think anyone ever really is. We all have things we wish we would have done differently, regardless of our religious or non-religious views. I've just had an opportunity, to really LIVE life accepting and knowing what the outcome is going to be but not giving up hope. I guess you could say that I'm at peace with it... (no pun intended)
That being said, I don't believe that those who would leave are necessarily bad dive buddies and I don't think that they would necessarily leave in any situation. I think they are taking the question quite literally and the answer they are giving is simply that it's better for one to die that two. According to all forms of training, that's the logical decision. They make that decision knowing it's something they have to live with. I just know that, for me, it's not something that I could do (not right nor wrong)....
As for the other topics... Would I protect a child from a bear? Yep. Would I run into a burning building? If I thought I could save someone - Yep And for those who are trying to convert SAS into motherhood... Come on... Be honest... There were times when we envied those who who were stading in the 60" line at the amusement parks while we were standing in the 36" lines.... (and my then 9 year old son sneezed and blew a booger on the woman's foot in front of me... She was wearing sandals - I was dryheaving...) (grin)
Ok -- Flame on and I'll go away for another six months...
