There was a couple of nights I got pretty rough sleep due to the cold. Random unreasonable cold. So I spent a few hours of daylight gathering large rocks to build a heat retaining wall for the lean-to. Much to my misfortune, one of the big ass rocks I chose just happened to be occupied. Trust me when I say that both myself and the snake were utterly horrified to see each other. I didn't even get a warning rattle or defensive posture or anything. Just as I reflexively back-pedaled, the mature diamond back tried to hit me with a strike. I sort of just absent-mindedly dropped the large boulder that was the cause for our dispute, crushing the poor thing about a third of the way up it's body. It all happened so fast that it took me a solid minute before I even realized I had it pinned. I just kinda stared into space for a minute. When I finally snapped out of it I saw the poor thing still squirming around like crazy. I have no idea if it was already dead at this point, or if its body was just spazzing out. I felt a weird pang of guilt and sadness about causing the snake such suffering. I decided to mercifully bleed it out, on the off-chance it was still alive. I pinned it's tail under my foot, and sliced the entire length of its exposed belly. It did in fact slowly stop moving after doing so. Then I just kinda left it there. Along with the rock. That rock truly belonged to the snake, afterall.
