So I have been doing a massive amount of research on the Divisions of the German SS during WWII. It is a massive undertaking with a very broad and information hit and miss. But while researching I was reading personal account, memoirs, unit history, deployments battles. They were not just confined to Germans, Arabs, Dutch, Scandinavians, and even French(who ironically were defending the Reichstag during the fall of Berlin.) Once such unit in particular, the 36th SS who were just horrible. Better known as "Einsatzgruppen" Lead by a sadist and convicted child molester. So I started to read a book called "Master's of Death" which is about Einsatzgruppen and there colorful history of state sponsored genocide across Eastern Europe. Now I already did some holocaust research and watched many History Channel specials on the subject but not in this detail.
1st hand accounts of a soldier stabbing a infant with a bayonet then parading the dead baby still impaled on the bayonet through the streets. Sardine Packing in which they dug a trench, put a group in front of it at the edge of the pit so when they shot them they would fall in, be covering in dirt then bring in the next until the pit was filled. Often times making the victims dig there own mass grave. They would have competitions to see how many one man could killed in one day, and some getting over 500 kills in a single day. Then playing the same to next day. Women and children raped to death then shot. Gathering Jews into a single building then using flame throwers to torch it and shooting anyone who escaped. The entire book is just a train wreck of dead orphans and puppies. 3 times I had to put the book down. You think, "The good guys will show up to save the day right?" No it's just death, murder, rape and more fucking death. The horrible fact about these men is many disappeared or were never apprehended. However after reading the entire book cover to cover I feel 100% more enlightened and more humble after the fact.
So my question is, have anyone you done research into a subject only to just stop and rethink or discover something you wish you never had?
