I'm not sure I agree with you. Normal people abuse children? Seriously?
Most abusers wouldn’t meet the diagnostic criteria of any disorder, yes.
Of those that do have disorders, it’s rare the disorder caused -or even played a part in- the abuse.
Most abusers are simply cruel selfish assholes.
Many others simply didn’t know any better. <<< This one is why parenting classes are the first step in most child abuse and neglect cases. If they take the classes and are still abusive? The courts now know it’s not ignorance, but deliberate choice.
The biggest trick / rule of thumb in asshole vs disorder? Do they confine their abuse to specific people (their own kids, spouse, people under them at work, etc.) or do they treat
everyone exactly the same? Because disorders don’t turn off when they go to work, or their boss is present, at friends homes, in front of the neighbors, etc... and turn on when they’re alone with their victims.
Abuse, rape, etc. are seperate things in nearly all cases. Sure, some delusional disorders, some brain injuries, some developmental disorders make a person
unable to discriminate. But even most sadists, aren’t
also abusive, as there are countless consensual and constructive avenues people can -and usually do- pursue. The choice to abuse others, for most people IS a choice.
There’s a leeeetle bit of wiggle room in substance abuse disorders. A lot of people are mean drunks / only abusive when they drink or are high. Still, to my way of thinking, that simply backs the choice up a step. As few people are stupid enough not to realize that when they drink they hurt people. If you only hurt people when you drink? Stop drinking.
I'm realizing that it wasn't an accident that I didn't have a social life when I was a kid. My mother was actually making choices to deliberately keep me from having any friends or getting out of the house.
If it helps at all? Isolating their victims is almost page 1 in the abusers handbook in domestic violence & child abuse. It’s not weird, at all. It’s a lot stranger for abusers to encourage a rich and varied support structure outside of themselves. That
does happen. It’s just not very common. And it usually comes along with other avenues of control that counteract (like transportation and finance).
