Back in july my dearest friend was killed by such a person who I think was influenced by this very same cult.
But nobody is willing to publicly admit it. Even myself I cannot say what, where due to the openness of the web and the upcoming criminal prosecution, and that very same person almost killed me. Still recovering with many wounds. I think its very possible he was influenced enough to make him a believer in performing such acts.
So sorry to hear that. I hope you will get justice.
My condolences for your friend and I hope you recover fully.
