Why is Child Abuse from Parents Still Happens Frequently?

Many people still experience abuse from others around them, including some who experience abuse from their own parents. Not everyone comes from a happy, loving household or has healthy, nonabusive relationships with their parents. But what is abuse? Abuse is defined as a violent act committed repeatedly against one party by another. Every year, more than half of the children in the world between the ages of 2 and 17 are victims of child abuse, yet parents still aren't aware of their mistreatment towards their own children.
