I think your T gave you some really good advice. The majority of people have a mix of good and bad traits (which I would prefer to lable as undesirable). In my life I have met two people that I think are truly evil. One of them I have known since birth (I am slightly older than he) and even as a toddler he displayed aggressive and violent behavior. He's in his late 30s now and his behavior has not improved and quite honestly I couldn't come up with a single redeeming quality if my life depended upon it.

But I think that these people are few and far between. One of the kindest people I've ever met I dismissed immediately when I met him. He was a co-worker and I was forced to get to know him because we ended up working closely together for a long period of time. He had poor communication and social skills and the things he said came off wrong.
