Evil Morty Theory

In one of the later episodes of Rick And Morty, Evil Morty gets the blueprint of the omega device. A device that can kill someone across every reality. So I have 1 question about this. Who does Evil Morty want to kill? Obviously Evil Morty wants to kill Rick but does not because in his words “You think I want a bunch of Evil Summers coming after me?”. So if he does not want to kill Rick Who does he want to kill? I have a couple theories for this one. Theory 1: He wants to kill his whole family. In earlier episodes Morty has started to feel like the house does not care about him. So as an irrational kid with ultimate power i think he wants to kill off his house. Theory 2: He is keeping it as a deterrent to his family. He may be using it to keep his family away from him so he can have an ultimate relaxation because his family is a source of stress for him. Theory 3: He may be using it to destroy the bug federation. Beth and RIck seem to have a destiny of being a space warrior and genius that don’t adhere to space governments so Morty could be following the same path. Thank you so much for reading this. It warms my heart that all of you read these goofy theories. I recently made a game for most browsers link here enjoy https://avoidpuzzle.blogspot.com/p/play.html
