I suppose it depends on whether the behaviour is learned or is a wiring problem.
Male sexuality, fear and agression all pass through the amygdala.
We know from studies of toxoplasma infection in rats, that the parasite can rewire a male rat's amygdala so that instead of a fear response to the smell of cat piss, the rat becomes sexually curious about the smell of cat piss, and the toxoplasma gets itself into a cat's guts - the only place where it gets to have sex with others of its kind.
Ref:
A person whom I know has a genetic identical twin who is a full on psychopath (and abuser), the guy whom I know isn't, which shows that the same genes and same environment are not sufficeint cause for psychopathy, a third factor must be present. The person whom I know, suspects that brain damage, perhaps during birth, might be a necessary third factor.
In the case of the brain damage hypothesis for psychopathy, perhaps it is the lack of inhibitions rather than an urge which causes the problems.
The question is then, whether there is sufficeint in their heads to absorb and retain inhibitions if inhibitions were taught to them?
I don't know.
If the behaviour is learned, even if it is in the form of acting out traumas - then yes, I think that probably is treatable.
