Lawbreaking Part Two

Hey guys so Stitches is Oliver (Me). Sorry I forgot to sign my post... oops.
I'm curious, because many of you brought up the issue of killing someone. Why is killing someone wrong? Don't murderers deserve to die? It doesn't make sense to me that in our society killing is viewed as wrong, yet someone who does so is in a sense given a secure home, bed, and has all of their general needs met for life. Does that punishment really fit the crime? This kind of turned into a question about capital punishment, but I'm curious to here your reactions. (And yes, I do agree, but I don't understand WHY...)
So... why is killing wrong?
