Timber, you might be right on that, but my entire life, no snake has ever tried to bite me, I used to catch baby cotton mouths by their tails, my mom of course always killed them, but I also understand they are deadly, and I was still young then, the last snake I caught, the timber rattler, was due more to find out what it was, and I caught it in the jar with a stick, and no, I have not seen anyone bit by them.
as for killing them, I disapprove with it, my reasons are simple, 1. with out the captured snakes, we could not make anti-venom, 2. they do help keep down rodents, and 3. if you kill all of them, it is disrupting the food chain, and can cause more damage in the long run
