Not all of them realise they are doing it. I mean the behaviours aren't accidental, but I don't think all of them realise that they're being abusive.
Even the ones who want control in every aspect of their lives don't always realise that by demanding that, they're abusing someone else. They're just trying to protect themselves.
My mother is the most abusive person I've ever met, yet she considers herself a victim and, when I used to see her, would cry and tell me just how alone she was, how she had no one, how no one cared about her... and she really believed it. Yet she was the most vicious, spiteful, self centred individual I've ever, personally, encountered. Hierarchical and predatory self esteem describe her exactly.
The same goes for my exH. He considered himself to be 'a good man' and believes he spent our entire marriage sacrificing himself to meet my needs. And, on the surface, he does appear to have made many sacrifices. But they were all to meet needs he imagined me to have, rather than the needs I did/do have. He didn't value me as an equal. I am a woman, and therefore I am weak, vulnerable, in need of rescuing and protection. I deserved to be protected from real life in order to protect my innocence... and when I 'ungratefully' rejected this, boy was I punished!
But I really don't think for a second he got a 'kick' out of the above. I do think he got a kick out of the punishments, but that's becaue he was angry with for not allowing him to nurture and protect me, and for letting myself down in rejecting my femininity...
I don't think it's that easy to dismiss cycles of abuse either. People have to recognise it before they can choose to reject it. Otherwise, it's just the way things are.
So my exH's parents were alcoholics. He spent his whole childhood protecting them from anything that might upset them because he feared their reaction. They were also loud, brash and aggressive. He wanted the opposite of that for his own life. He'd become conditions to 'fix' and to protect. He genuinely thought that I was unusual in not wanting a man to scoop me up and protect me from the world entirely. I mean, who wouldn't want that ?!!
