We discussed this in my crim class this semester. I say let em all rot in prison for life. Most of the time prisons aren't that well taken care of as most people thing and the quality of lift isnt what its made out to be.
2nd, in order to kill someone it costs 5x as much then to keep them there for life. (You have to let them appeal teh crap out of their case b4 u can kill them and that costs a crap load of $ from teh state)
If you admit it, then you give up any rights to a appeal. Make them dig the hole first then its 2 shots to the back of the head.
