The law of biogenesis, simply stated, is life begets similar life. That is an established scientific law. That same law is also applicable in the moral field. Aberrant behavior begets aberrant behavior. Licentious behavior begets licentious behavior.
Criminal behavior begets criminal behavior.
Behavior, by its very nature, is learned. Aberrant behavior is also learned behavior. That s why alcoholics tend to produce children who become alcoholics. That s why those who molest children were often first molested as children. Behavior is learned at a very young age.
