Glad to see this isn't a total zombie thread as it'll be good to get it off my chest to people who will actually believe me and take it seriously.
My sister's ex is, without doubt a sociopath. He's got convictions for beating her senseless. There was heavy social services involvement because they have two kids together.
I don't care what anyone says, his eyes are totally dead. He's Mr happy, jolly joker who everyone loves but it doesn't matter how much he's acting the goat his eyes are completely expressionless. Total attention seeker, actually calls himself an actor because he has a role in the annual pantomime.
I acted as my sister's advocate during core meetings with SS. He sat there and bare faced lied about me. Huge whoppers of lies. I would be absolutely dumbfounded that he was saying these things with me sitting right there. Him knowing that I know he was lying but doing it so glibly. When their second child was born (emcs) my sister crashed in recovery, her heart stopped due to internal bleeding that hadn't been noticed. While the crash team was rushing her to theatre he sat and calmly ate a sandwich. Didn't blink or even let any of us know she was in such danger. She was clinically dead for 12 seconds, so a pretty serious incident.
One time I called him out on his behaviour, it happened to be during a phonecall but he got so angry with me I had to hold the phone away from my ear - he was absolutely raging. I've no doubt if I'd been in the same room I'd have been physically attacked.
There are so many incidences of violence towards my sister (including broken bones) and every time she'd.make excuses as to what happened and he'd sit there without flinching, all the time knowing the elaborate excuses were lies and he was responsible for all of her injuries.
He's got a new girlfriend now who believed his conviction for assault were all my sister's own fault. My sister saw them recently. She was sitting in the back of the car crying (he used to make my sister sit in the back when he was angry with her) and he had hold obtuse steering wheel with a murderous look in his face. It's.clearly happening to her too now.
I despise him but his charm meant after he broke my sister (and he did) he won custody of the kids. Thing is you say you think he's a psycho but people assume psycho means Ted Bundy or Ian Brady and because he's not a serial killer, he can't be. I've got his number.
