I don't think it is a trait of BP Disorder, but definitely talk it over with your therapist.

I hate when someone kills someone and the media comes onto say they have BP Disorder.

I think that the people who actually kill someone have a personality problem not related to BP at all.

I know I have a good heart and that's part of my personality and I would never kill another human being.

However, if you are having these thoughts and they are intrusive, talk to your therapist about it and find ways to deal with the thoughts. Intrusive thoughts are the worst. I absolutely hate them.
