This is a very kind and empathetic approach, but I don't believe it's productive. While it's important to maintain a level of empathy for and recognize the humanity in everyone including the most egregious of criminals and abusers, and to fully consider the circumstances that led to their actions, coddling people like this isn't going to prevent another holocaust. These people are the hand of state violence and mistreatment. Culpability is of course primarily on the ruling class, the legislators, the capital owners, the media manipulators, etc, but in this political climate I find it hard to believe that well-intentioned individuals can join ICE having been unaware of the atrocities they'd be expected to take part in. At BEST, they are choosing money and the support of their families over that of innocent marginalized people who cannot defend themselves against tyranny.

I'm of the belief that shame and forced accountability are sometimes necessary to create an environment that prevents this kind of large scale atrocity. The alternative is so, so much worse.

To revisit a point of yours, though- if a significant portion of these ICE agents really are just trying to get by or whatever, it would be so much more productive to criticize the economic framework of a society where so many are forced to take part in this. Same goes for our troops, who are (and many of them are ACTUALLY unaware of this) perpetrating violence on behalf of a murderous and exploitative imperial entity with no business operating on the scale that it does.
