Yes political violence is NEVER justifiable. That is the one and only correct answer if you wish to live in a modern society. And believe me, you do not want to live in the other kind
The question is not limited to modern society! Or even humanity! Just “ever”. I mean what does the universe even look like in hundreds of millions of years? Humans won’t even be around.
That is an insane take. So according to you, for example, it wouldn't have been justifiable for jews to carry out violent acts against the Nazi regime during WW2? Or any other oppressed people do so?
