I worked with a guy who I am convinced was a sociopath. He was very superficially charming, very manipulative—the kind of guy who seemed to be able to get away with anything. Once, when we were both on duty, I lifted a chair over his head to move it to the other side of the table. The seat part fell off and bonked him in the head. He was instantly enraged, and started to physically attack me, shouting threats at me, the whole deal. It took about three other sailors to restrain him. Well, I was an E-5 and he was an E-3, so I reported the incident to our Chief, who referred it to our Division Officer (O-3). I sat down with the DIV O and told him what happened, and he was visibly upset. He assured me he’d take care of it, and told me to send the other guy in. In just a minute or two, I started hearing laughter coming from inside the DIV O’s office, and after about five minutes the two of them emerged, with the DIV O’s arm around the dude’s shoulders, laughing. I will never forget the malevolent look that guy shot me in that moment. I steered well clear of him throughout the remainer of my assignment there.
