Those who are abused -- in the future, they abuse.
Those who were teased -- in their future, they tease.
Those who were molested -- in their future, they molest.
Sometimes, I wonder why this is, especially for molestation.
One reason, I believe, is this:
Subconsciously, the molester who was molested definitely isn't happy. And when he see happy children, he's often jealous of their happiness and wants to take it from them.
