I note that you have failed to establish that the death penalty is "wrong". I assume you are dropping that claim, which means you lose the debate.
And no, the purpose of the death penalty is to punish capital criminals. And no, killing is not a crime;., murder is a crime, with murder being defined as the unlawful taking of human life. Surely, you do not believe killing animals for food is a "crime"? Nor do you believe that killing man to stop him from raping your wife would be a "crime". It is certainly not in the U.S.
Capital punishment is just because God says so. And I am not trying to stop killing. I am trying to punish capital criminals. I have no problem with killing, especially cows and chickens. You will have to do better than that.
This is my first debate so I am not as good as others but I must state that prison is a much better way of discipline than killing. You are taken away from your family, have to follow a strict regime and are in with a bunch of strangers. I am OK with that as at least you have a longer life and I think life is the most important thing in the world. Without life, you can't enjoy even the simplest of things. I agree that something must be take away from criminals, but life is too important to take away from anyone.
What you think is not relevant. You have done nothing to show the death penalty is wrong or evil. And the fact is that those in prison have shorter lifespans than those not in prison, which means even your prison sentence is a death sentence, but you prefer the slow and torturous method and me the quick and easy method. You also want to make the criminal suffer. That is evil. I just want justice.
