My son's life is worth everything to me. I'd sacrifice myself, happily and without hesitation, and kill without hesitation, to save him.
Next in line is my wife. I would certainly sacrifice myself to save her, and would certainly also kill to do so.
Next in line are my friends and family. I would kill and put my own life at great risk to save any of them.
Next in line are the lives of "innocent bystanders", particularly women and children. I would put my life at significant risk to save them. For example, if I was at a mall, or a school, and some nut with a rifle started stalking about shooting people, I would use every possible tactical advantage to take him down (RATHER than run away and save myself). I normally carry a Glock 29 with me; sub-compact, very powerful, but not terribly accurate at anything more than a couple-dozen feet. In engaging someone with a rifle, I'd be at a serious disadvantage. But I would try, possibly at risk of getting shot and killed myself, which is fine with me. If I didn't happen to have my Glock with me, I'd try to sneak up on the gunman and use my knives (which I always have with me, two 4-inch Cold Steel combat folders, plus a 5-inch backup folder I keep in my left boot), preferably rushing him when he was reloading, or distracted; in that case, I might have to "let" him shoot more people towards getting to reloading before I rushed him; and the deaths of everyone that was killed while I waited for the opportune moment would haunt me forever. If the gunman was actively shooting people, especially children, I might even try to rush him knowing full well that I'd get shot, possibly mortally wounded, in the process. But if I thought I could keep going for long enough after being fatally wounded, if I was close enough (it happens) to get one of my knives in his neck, I might chance it. AND, I'd be trying very hard to freak him out enough to be a poor shot; it's hard to be composed when someone with hellfires burning in their eyes is rushing at you, bellowing in rage, holding a wicked looking knife in each hand. Like I said, especially for children.
Mark Allen Wilson is one of my personal heroes. He actually did what I just mentioned, engaged a rifleman with a .45 caliber pistol, placing himself at great disadvantage (given his background I'm sure he realized this, and he was actually killed for doing so. That's what I call a good death.). The rifleman happened to be wearing body-armour. One of the reasons I carry a 10mm Glock 29 is that it is quite a bit more powerful than the venerable .45 ACP, and I do have rounds for it that I think would penetrate anything up to type IIIa ballistic armour (type III or IV, and I'd still be screwed.)
As for my own part, I put little value in my own life. The only reason I exist is to provide for my autistic son, who needs me right now.
I hope it is clear that I've considered these scenarios previously, and very carefully.
Good fortune,
