As far as suicidal thoughts go, I feel that if a Master is that mentally unstable, the playing should stop. I had a very close friend that showed a lot of signs on this red flag list, including suicide, and felt that had I of submitted to him I would have been used as a punching bag (if you will). On a friendship level I was willing to help but on a Master/slave level I could not allow it. Love this post by the way. Very helpful
