Hey man sry it took a while to get back to ya. Yeah I seem to do the best when I am alone as well. I also notice though that sometimes when I am alone for awhile that I will think too hard and ruin my inner peace. You and I both need to realize the fact that we do feel sorry says enough about our mistakes. Although it is tough to understand the intrusive thoughts and what they mean. Next time you watch your brother try this technique if you want and see if it helps. If you get nervous and say to yourself, "gosh I really need to watch myself because last time I actually thought that I was goin to do something." or if you just have the normal nervous thoughts. You should let them come, invite them in and then let them pass. I believe that you have to will power to distinguish right from wrong. If you don't think that you do, then it is only because you don't believe in yourself. So if you think that you are up to the challenge then let your thoughts come in and answer them. I don't know if this helps or not, I am no psychologist, but when I was having these thoughts I was really nervous about them and the only way I knew how to cope with it was to let them in and deal with them one at a time. This doesn't make them go away completely but it should reduce them and it should make you feel better about yourself when you know that you are not the person that your intrusive thoughts make you out to be.
