It's wrong to give "the State" the right to take a life. Period.

My opinion, of course.

To be sure, there are crimes so heinous that the perpetrator can no longer be allowed to roam freely in society. You might even believe that, from a moral standpoint, they have forfeited their own right to life. But you still don't give the state the power to take it.

There are plenty of arguments for why you should not allow this, but, just an obvious one, in doing so you also give the state the right to take yours.
