As with the Nazi's, there was heavy corruption and little to no control of the SS or enlisted soldiers, so the SS and enlisted men misused and abused their power and authority greatly. So much that many people, citizens, and even other soldiers, feared for their lives around the Nazi's or higher figures/authority, mainly because they were unable to be stopped in anything they did, as in murdering people, stealing things, and other things that may be considered morally wrong. Hope this helps!
