Then we agree on a lot of things. It is true that these tyrants and fascists will only respect violence, so sometimes that is what we must use - to defend, and sometimes even to attack to prevent even worse things. I cannot see any fault in what Ukraine is doing right now for example, they have all the right to attack Russia back. But targeting schools or hospitals like Russia does? No, that would be unacceptable even as a counter.
My point is more that even the nazis still got a trials after the immediate warring was over, before they were hanged. We cannot just start random murdering, it has to be based on the moral rules we are trying to uphold, or we lose the things we are trying to defend. Where the point is when violence is needed, then, is the better question, yes
