If you think murder it’s easy to define, go look at how many different kinds of murder are defined in the US legal code and how every country defines it differently. And military kills are excluded even though definitively I fail to see the distinction between a war and political violence - it’s just external instead of internal. What is and isn’t murder is surprisingly hard to define and you’re either using a legal definition that’s a political compromise of different ideas or your own value judgement which is your opinion and not necessarily one shared with others. Seriously - try writing down what you think murder is in 3 sentences or less and see how far you are away from the legal code in your country.
