Two points
Firstly the people of Europe are not a united front in anything and there is a plurality of opinions and positions on just about everything, including the current conflict escalation between Israel and Palestine.
Second I think it’s of utmost importance to differentiate between people of a nation and the government of a nation. Im this case the people of the nations were behaving like assholes, true. But Israelis as a whole are individuals with individual opinions. Like all inhabitants of all states.
People seem to forget this in times like these. I know of people that were scared they were going to be attacked (and they did get attacked sometimes) for looking Asian in the first months of corona. Now I almost never hear Russian on the streets in my city. And if I do, people are looking.
I feel bad about this development.
I think you are looking for the word duty or responsibility. Not a native speaker but there is a word for something that you have to to when gaining rights.
