Should there never be forgiveness for the ss guards in German concentration camps?

I originally had a modicum of empathy for young SS recruits, as I imagined they'd been effectively brainwashed since childhood by a fascist regime and didn't have a properly developed moral code. I also imagined the punishment for refusing an order would be severe. I then saw a documentary that told of several young SS soldiers who outright refused to mistreat people and all that happened was that they were given temporary cleaning duties in the barracks. At that point, I realised these men had every opportunity to refuse orders and also possessed an inherent morality that told them something was wrong. If just one could refuse, then they all had the choice to refuse.

So no, these vermin deserve to be thrown in a hole for the rest of their sorry lives, no matter how old they are.
