While there is a moral imperative in regards to the sanctity of life, there is no such in regards to private property. Property is not life.
So, stealing is OK, then? Or vandalism?
If human is sacred, then along with abortion, a truly ethical person would also oppose the death penalty.
I suppose that could be true, if you make no distinction between the very worst violent criminal,and the most innocent, defenseless child. I think I can safely speak for all sane, decent people, when I say that there is a very significant distinction, here, that you are trying to deny.
In any case, it is the one who defends murdering an innocent unborn child but who opposes putting a violent criminal to death, who has some explaining to do. But really, what more explanation is needed there, than to recognize that such a person is simply evil?
