Or, they can turn around and try to impose negative consequences on the people who are trying to impose negative consequences on them. Which, one might argue, is exactly what is happening in several state legislatures in the US right now. And then the fight goes on until one side wins, or there is some sort of "peace deal".
But I wouldn't frame it as cause-and-effect like that: one side doesn't attack the other as a response to experiencing consequences; they attack the other pervasively at every opportunity, and sometimes experience consequences for doing so.
Please don't empathize with me, though. I don't need it :0
If that's a fair comparison – society's future isn't looking bright.
Don't be surprised if Hitler doesn't empathize with you either, you have only yourself to blame!
