Yeah, but you can also find that rate if you remove the trigger (abuse) from the environment (society) and see how the rate changes.
You don't have to lock someone in a coffin, or something ridiculous like that (and that would be counterproductive anyway). You create a society, or a least a sub-society, where there's no abuse, and see how much abuse is invented by the people raised in that environment.
That's presuming the only influence on a child's development are the adults who are raising them, which is not true.
Let’s put it another way, if a catholic priest touches a choirboy, it’s not a good idea to let the choirboy become a priest and victimize the next generation of choirboys.
Gross but perhaps a benefit to society
