Sins of omission are far more dangerous than sins of commission.

This complements the thinking that to turn ones back on your responsibility can be worse then the act itself. When we look at the impact of neglect and absence on the psych of a child, there can be no worst crime then to let it continue.
The unusual thing I have found are those whom are struggling with inner torment seem to falsely believe that they have gone unnoticed and it would be better to double down. What commonly is missed is they become more predictable the further from the path they walk and the more they repeat the same action.
