Hmm.
I just realized that I've never killed a single digital Hitler. A digital Hitler did once give me the Iron Cross, though. Odd thought.
Honestly, I might need to think more about the pain and suffering I've caused than the actual body count. My cruel DF experiments for one(I once set out to break every bone in the body of an enemy and bite it's head off as the ultimate display of brutality to show one of my friends how brutal the combat was... I met many failed attempts on intelligent creatures, and some successful tries on small animals.)I don't consider a fort finished until I've made a goblin torture room. I've built giant, extremely inhumane animal breeding and processing plants in minecraft of all things(e.g. The automatic chicken breeder and cooker). I've let hundreds of rookies die in X-com to keep my veterans safe, and I've incurred large civilian casualties. Hell, I've nuked civilians! In fact, when I play Civ 5, I use nukes more than Gandhi! Wait, how many soldiers and civilians have I subjected to bombardment by artillery (mine(I put the art in artillery) or otherwise)? Do you know the psychological effects of warfare? I should be ashamed of every domination victory I've had.
By Odin's beard. The time I conquered Europe starting as King Björn Ironside in CK2. I exterminated royal houses. I used thousands of soldiers as pawns and subjected them to diseases, sieges, and more primitive bombardments of arrows and boulders. Boiling lead? What have I done? The religious persecution I took part in. I completely destroyed the Catholic faith! The pope sat in the Germanic theocracy of Rome (owned by my dynasty), with Norse children laughing at him in his pointy hat. I imprisoned/ransomed hundreds, if not thousands of people. I committed incest for an achievement! Those poor kids.
