Those who have had to deal death tend to be the least likely to want to do it..Kalaznikov made the news when he died late last year. He had a bravado front about not feeling guilty, but apparently wrote his pastor, desperate for forgiveness for the lives that his 1947 invention have taken over the years in service to evil. It would be hard and perhaps impossible to find a historic use for the ‘47 that wasn’t by some group that wanted to take over or terrorize people, rather than to save people, establish rights, or representative government. The standard use was to enslave or wipe a group out. .A heavy burden, even though he had no control over how it was used..Most humans don’t want to kill other humans, period. Humans have an inbuilt proscription against murder. Those few who don’t are called criminals, Socialists, or abortion doctors. Most who kill have guilt to one degree or another, even when it’s the shooting of a criminal to stop them from beating an innocent to death..That guilt about killing people manifests in some weird ways. Some self-destruct. Some serve others with vim and vigor. Others adopt religions that allow them to kill .One wonders how many killers went Socialist to assuage their consciences— being able to rationalize bestial deeds for the “greater good”.
