Depends, sometimes i just think 'screw it, they deserve a kill' and stick around to die, sometimes i want to land my kills or i dont think the enemy deservs a kill, then i will retreat and not feel bad. I only feel bad when i am forced to run, which never happens anymore. i just either win or die.
just yesterday, I found myself out in the middle of FT, and took out a couple of nits....ya I could have run home and landed my kills, but it is just not how I am. Someone mentioned on 200 (in a fun way), the person I had just previously shot, that they were coming back for me. I knew, seeings how I was the only rook in that area, and by the bar, that I would not be walking away...even though I could have. Sure enough I ended up fighting, died, but had a great time. everyone got back what they wanted, I got a good fun fight, and the "bad" guys got my scalp.
I would probably have stayed anyway, but after taking a few scalps, I just felt it would be kind of wrong somehow, to just leave the area because I was worried about dying. I still had gas, still had ammo. Truth be told, I could have grabbed alt, skirted the area and done all the things that would greatly increase my chances of living. It's really just more fun, for me and others, to be that guy, who doesn't do the things to ensure their survival/landing kills, and go out in a blaze of glory:)
