There is some Irony here. German SS guards had a hard time shooting children. Some Nazi SS men could do it, but others had a hard time convincing themselves they were killing future vermin when they looked into the eyes of children who looked just like their own back home.
Convincing themselves they were doing the 'right thing' was necessary for most SS men to become cold-blooded murderers. But convincing yourself kids deserve to die is hard to do. Human self-deception, despite having great power has limits when it comes to kids.
The stress working on an execution squad eventually made the use of gas necessary. The de-personalization gas provided was necessary for the increased production of later years.
In 1941 a SS group leader was told to get his men ready to shoot a group of Jewish children. The group leader explained the morale problem and recommended a group of Ukrainian Guards shoot the kids instead. There were no objections to his suggestion.
I wonder if the Jew Killer I met in Seattle in the late 70's from Ukraine was one of them. If so he took too long to drink himself to death. Wen he got drunk enough at the Blue Moon Tavern it was all he could talk about.
The irony is German SS men having more qualms about killing children then the leadership of the American Democratic Party. Saying more may be going to far? The same then. That does not go too far.
