Exactly. That is why for many crimes if you hide the criminal after the fact, you become part Of the crime. Children need to be taught how wrong it is and how if they are post puberty and even do this once, they may lose their family, if not their life. Child molestation is even hated by murderers.
When you think of the dynamics of when the main breadwinner of the family is the perpetrator ....then you can understand how many spouses, usually women — would hesitate to “notify the authorities.” To do so would mean a loss of income and support as well.
At least this was the case in my own family.
So it was best to keep things quiet. The problem is, you have to sell out your kids to do so.
It’s a vicious cycle in many lives and many families.
