That's the weird thing. There's millions of people who would never hurt anybody up close and personal, but happy to keep hurting people far away by their choices. The same disconnect often applies to the negative consequences that hit them.
In those cases, if they're family, and you're used to seeing them, you can find yourself having superficially friendly interactions, they will be genuinely happy to see you, etc... And they will vote for death camps without a single pang of conscience because it seems like the normal thing they've always done.
I don't think they're the majority, but they're certainly numerous enough to be the primary enablers of a fascist takeover.
