>Eichmann presents that he didn't like it at all, but really had no choice in the matter if he didn't want to be made a pariah or face severe personal repercussions
Which by the way was largely false, for both low and high-ranking Nazis. It was usually possible to slowly or even quickly distance yourself from directly committing atrocities (or coordinating them) and get fobbed off into some low-key administrative position without fearing anything like serious punishment. The Nazi machinery was harsh towards openly voiced disobedience and discontent, but surprisingly tolerant of a "weak stomach" or a lack of what their fanatics called moral fiber (being able to protect the race by butchering innocent others).
Christopher Browning in his book about Reserve Battalion 101, mentioned in the comment right above yours, emphasizes this point about a lack of severe punishment for not participating, repeatedly about the members of that death squad.
The ugly black magic of the Nazi system was specifically that it often made previously, otherwise ordinary people internally normalize mass murder into something they could do.
The above aside, image too the kind of empty shell of fundamental human morality you'd need to be to continue sending innocent people, including women and children to their deaths in gas chambers, just so you can avoid looking bad on the social scene around you.
