Viral social constructs

I wonder what makes some social constructs perpetuate..  I've heard people who are molested as children are more likely to become child molesters.  Such an evil act, I wonder what causes that.  The same can't be said for victims of other crimes, like rape or robbery.

I suppose whether the victim enjoys the act determines the likelihood of performing it themselves.  Just as a drug addict enjoys the high and then seeks the experience again.  Very simple logic.

With such insight (arrived at through uncomfortable means, but found nonetheless) it makes me wonder if the victims of less enjoyable acts, such as rape or robbery, are more likely to become perpetrators if they found the experience somehow pleasurable, e.g. if they were high at the time.

I'm probably giving such a simple notion too much credence.  This is simple Pavlovian behavior analysis.
