It is hard to tell if capital punishment has such an effect. And even if, in some contexts it has (such as in the American South with a very high incidence of murder), this effect may very well go away if a decent welfare state was replaced for the existing social order.

The democratic thought is based on that 'ordinary people' are suitable to rule themselves.

I believe that one basic question, what we ought to do, period (the moral question), is a genuine one. There exists a true answer to it, which is independent of our thought and conceptualisation.

I am indeed a moral realist.

The Chinese are generally speaking much more reluctant than Westerners to killing as a means to the rescue of lives.

Global governance need not take a democratic form.

How could it be that I had a legal obligation to kill people I did not know, and who did certainly not consent to it, while my father's doctor could not help my father to die when my farther asked for it? My consternation brought me to moral philosophy and a life-long search for an answer to the question when and why we should, and when we shouldn't, kill.
