Is all organization you can think about organizing to kill someone? People have the right to organize themselves, regardless of their political views, whether it is a telegram group about organizing a school festival, or demonstration about a topic you agree or not agree about. You can also ask to ban phones because people can use them to organize a murder. Or ban a postal service, since postal mail can also be used for bad purpose.
