I don't really know why the regret. I was certainly justified, and it happened so quick. What I didn't mention, and what made the snake's behavior so bizarre, was it was a good twenty feet away when it started the charge. And a rattle snake can really scoot! I do eat meat, have no problem with hunting, all that. But ANY unnecessary kill is unjustified. Did what I did. And also, maybe 'cause I'm over the hump now, sometimes I think back at the deer and elk and rabbits, and game birds, and black bear, that I snuffed out. I DID enjoy eating them, never wasted game, took care with my shot and didn't take it unless I knew it would be dead from that one shot. Ducks, grouse, pheasant, chucker, quail, dove, are an exception to that. Throw that lead! Ah well, fun from my past.
