Priebke is quite a unique example. Most nazi's who took part in such behaviors had other options: for example , many could have chosen not to be part of the "death squads". This might mean they would advance less in the ranks and might become regular wwii soldiers which isn't the best life.

Priebke got hit orders from hitler. Altought there are a few who disobeyed a direct order from hitler and lived to tell about it, Priebke, in his a circumstances would have probably been executed.
