Have you tried attacking it and attempting to kill it? I visualise them burning up from the inside with fire then cage them and send them through the sun, which is a portal to the black hole in eh center of the universe, which destroys their pattern enough that it’s can’t reform and the spark but start all over again as a different being. (Spirit is immortal, but the shells are not and it’s the shells that pick up all this ego stuff baggage that makes them weird)
In the case of an attack using humanoid avatars, use the concept of the “soul sword”. You will see this in fiction buy I got the ideas from E.A.'s work. You keep it in your heart - reach in and produce a flaming sword that is made of your own inner strength, convictions and sovereignty, can cut through things like a lightsaber - kill it with that by stabbing it then cutting it up into pieces, yeet the pieces into the black hole via the sun. Reflect it’s own anger back at it - it deserves it not you.
This here is why you are justified to kill it. It’s been warned and told it’s not to do this and attacked you anyway. You now have the high ground and the spiritual right to defend yourself. This is a powerful rule in the universe, I found, that once attacked there’s no protection for the attacker, you are sovereign and the victory is already yours to take.
