Your viewpoint is self-centered and myopic. I don’t believe it to be immoral. You do. But you do not get to define morality. And I want unrefuted citations on executions of innocent men. For every convicted criminal on death row (Ruben “Hurricane” Carter comes to mind) there are plenty of people on the other side providing facts that cast just as much reasonable assurity as the suspect’s claims of innocence.
Hopefully you’ve never had a loved one raped, tortured and then murdered simply by crossing the wrong person’s path. Go through that, then come back and tell me about peace, love an understanding for the humanity of the offender.
If someone goes out into the world looking for trouble then they should get it. And I firmly believe that removing them from the world is not a deterrent to others. That would require rational thought and criminals by their very nature do not make rational decisions. But removing them from this world does ensure that that particular criminal will never offend again. To me, that is a fair moral transaction. That is only my viewpoint, my definition of what is moral… yet I can sleep just fine at night with it.
Watch “The Cheshire Murders”, listen to the father’s viewpoints on capital punishment, it is exactly how I have felt on the issue for decades.
