Yeah, this again is a symptom of impotence and frustration. Wishing harm to anybody, even Hitler, won't do you or anybody any good. Back in the day it would have been great to just coldly and calmly find a way to remove him from power as fast as possible so that he stopped doing harm... but then would just removing Hitler have ended the systemic antisemitism in Europe? Did it even end? Hmmmm.... a worry for another post.Pretty sure lots of people wished harm on Hitler.
Sure frustration is what comes when you fail to do that, e.g. stopping the harm.
