It’s not asking for sympathy. It’s asking to understand that killing them won’t fix anything. We are up against ideas. You kill Hitler, someone takes his place. The world isn’t being run by great men who we can’t do without. It’s run by people. Shuffling the names around won’t really achieve anything, you need to destroy the thing that is giving them the power. The Ideas inside peoples heads that they need to be governed. As I put very succinctly in another comment. If we can destroy those ideas we don’t need to kill anyone as they would be powerless and if we can’t killing them won’t change anything. In fact it will just allow whoever comes after to use their death as a way to drum up support for wiping you out.
If you want vengeance then lets enact it on this plane of existence, where we know what is happening to them. If you want things to change killing individuals is simply not productive.








So all of your ideas are so simplistic that you think no-one will disagree with you? or do you think you can kill them before they can kill you? If you are an anarchist, decide to ally yourself with communists, and start talking about guillotining, I can guarantee you it’s only a matter of time before you’re called counter-revolutionary and get killed yourself. Or you could decide not to ally with them, in which case they get added to the list of people you’ll need to kill. Making it rather long. And you can be sure that sooner or later a charismatic autocrat will take your place and use it to consolidate power. Thinking that killing our enemies is a path to victory opens up so many potential vectors through which power could be consolidated. It’s just better to do without them.
