I personally don't have any snakes that will eat other snakes, YET, but I don't see a problem with it. it's the way life goes. My wife gets mad because I see people on Craiglist or facebook giving away bunnies they no longer want, and I tell them, if No one else wants to give them a home, I'll make use of them. I don't do cats\dogs etc, but bunnies, chickens, quail, etc I have no problem with. Again, I don't have snake eaters, but my rats get too big or too many for their growout tubs, I simply put them on carpet and whack the back of the skull with a hammer. I tried holding the neck down and pulling the tail up to break the necks, But I don't have anything good to hold the necks down with. For rabbits and bunnies I simply put a piece of wood across their neck and stand on it with both feet. Grab the legs, pull straight up and the neck cracks. No pain, instant death.
