when I was in psychosis I thought I was supposed to kill someone too because he was really the devil or something, like I would be saving the world......whatever your motivations are the delusions play on them. I once slept with my chefs knife on the night stand because of feeling monitored and that people were breaking in to put something in my head to cause the voices (like a transmitter in my tooth). This is why I stay on my meds forever what if I did something after getting confused due to psychosis....I had to make a promise to myself I would never take anything into my own hands ever again and would rely on the police and military instead.
