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?
