I just wanted to say almost everyone has the quick and fleeting feelings and thoughts of violence at some point in their life and that you aren't alone in that. I used to be so disturbed by the frightening things that would run through my mind. It isn't the thoughts that make you who you are but the way you feel and respond to them. Don't be too hard on yourself or think too much about those flashes of scary thoughts. I find I have them when i am hypo-manic or manic and mixed. I like you would NEVER hurt anyone and some of the thoughts I have had as brief as they lasted scared me a lot. I also can't help but to wonder if some of these things are just subconscious responses to what we see in movies and on TV. I hope you are feeling a bit better.
