.. all of the abusers I've known were cowards. That's why they pick on those that are smaller, weaker, less able to defend themselves. They're pathetic really.
Yes, they are cowards who know who they can abuse and who they can't. I really think that they hate themselves and project it on to others who are weaker and cannot stand up for themselves.
They beat down their victims literally and figuratively. It is like walking on eggshells when a victim is around this kind of person. The victim is made to believe that it is all his/her fault. The victim is persuaded to keep quiet because "no one would believe him/her any way."
The abuser is also really afraid of losing control of the victim. S/he will use whatever means possible to maintain the control. If the victim breaks away, the abuser knows what buttons to push to reign the victim back in. It usually involves apologies, gifts, being really nice. If this doesn't work, the abuser may stalk and threaten the victim, so much so, that the victim unwillingly returns out of fear.
In any case, this guy lost control of his victim. She was actually going to leave. To add insult to injury, she was taking the child; and he was going to have to pay a hefty sum to her. He wasn't about to let that happen.
I feel certain that he tried every manipulative tactic that he could think of. When she didn't bite, he was forced to kill her. Of course, that was her fault, at least in his own sick mind.
The last thing that I want to say is that many abusers are very successful. They hide behind this image and wrongly believe that they'd never be suspected of committing such a heinous crime or even of abusing their spouses.
Sometimes, it works; and sometimes, it doesn't. Hopefully, it won't work in this case.
