IME.. I prefer malevolent abuse :D As it's easier to simply hate the person, or care not a single whit about them in any form, and just walk away.
Unintended abuse/neglect can come from a wide variety of sources. Consider the child who is being beaten and raped... And does the same thing to another child. Or the recovered alcoholic who would terrorize her husband and children when drunk, but never sober. Or the single parent working 3 jobs while their children are home alone, day after day, night after night. Or the addict whose kids are starving while $300 goes up a nose or in a vein. Or the person with PTSD who lashes out in fear/anger at their spouse or partner. Things start getting murky... Don't they? When all of a sudden there are reasons, motivations, diagnosis. When the person doesn't want to hurt the people they love and is doing so, anyway.
It's one reason why I don't usually use my exHusband's diagnosis, and stick simply with prick/asshole/c*nt/douche/etc. Yep. There are very very good reasons "why" he is who he is. Those reasons don't matter to me. I was used to dating people with issues, who didn't want those issues bt also understood and accepted that they had them; worked very hard to contain/ redirect/ manage themselves, etc. It doesn't justify things, but it can cast a different light on a situation. So I mistakenly thought the same thing in my ex, for several years. I was wrong. My ex is a malevolent motherf*cker. So, f*ck his reasons. I've known sociopaths with more empathy. They might not be able to feel things the same as most people, but they took care to be careful of others. Like you may not be confined to a wheelchair, but that doesn't mean you run around tipping people out of their wheelchairs. You might not understand everything that goes into it, but you can reason through things like : stairs might not be a good option, here.
I prefer malevolence because it's "cleaner" in my head & heart... But when someone is trying to hurt you? Hope they've got the attention span of a gnat. I prefer accidental abuse in my daily life. Both are bad. Just in different ways.
