I do not think that we, imperfect humans, should have a say in who lives and who dies. We are not the one who gave them life to begin with. So why should we be the one to take it away? "Ye who have not sinned, cast the first stone." Jesus said this to a group of people who wanted to stone a prostitute. According to the Bible, a book we based our country off of years ago, Jesus was the only sinless Man, and only he had a right to cast that stone, but he didn't. Basically, we shall not kill. Regardless of the crime committed.
