I'd say that a loving husband and father who murders his wife after she cheats on him and fucks him out of his money and his house and his children in a rigged divorce court is really unlikely to re-offend, but I'll bet they have a very different opinion about that sort of murderer.

We all know which murderers they want walking the streets; The drug gangs, the armed robbers, the reprobates, the scum of the earth the whole world rightly executed until a few decades ago.
