I know too little history to add any corollary comparisons to such quadrumvirate of butchers, but I am already dismayed by what I know of these.
I know and understand so little. I take comfort in researching the past because it is easier for me to manage than the present.
I don't understand why anyone would want to lead a country, to be responsible for an army, to order killings. How does one rest at night after doing that?
I have read that <3% of people just have no conscience. They don't see people as like themselves, but merely as things. Things can be made to to amusing things, like beg for mercy, or squawk when poked or prodded just so. Psychopaths are incapable of socialization, and narcissists, something most psychopaths are, are immune to criticism. So I've read. I can't relate either.
