Are most child abusers

I would not care to say, because this is a very serious matter and clearly any form of cruelty to children is inexcusable; but as for motives, I do not make such "diagnoses" or general ""conclusions" as I am not a research or clinical psychologist, nor a barrister.....

no.
People seem to eager to label others as psychopaths as if they dont really know what a real psychopath is and instead what they see in films and so on.

I know the ones abused me were

I think so yes.

Hard to know without an actual diagnosis.
