Stalin was looking for excuses to kill people. For example in 1937 - way before World War 2 started in Europe - he ordered murdering of all officers in the Red Army. If I remember exactly over 30,000 people were killed. There was no enemy for Russia at that time. There was no war going on. Nothing. Just Stalin's paranoia.

Robespierre on the other hand was governing France that was on a verge of a civil war: monarchists vs. republicans/liberals/democrats. He was governing France that was in state of war with basically whole of Europe. Six foreign powers if I remember correctly attacked France at the same time trying to restore the monarchy. With monarchist in France - French people - supporting the foreign powers. You tell me there is no difference? Please elaborate.
