To be pedantic, child sexual abuse is the vicious crime. Pedophilia per se is, I would say, a part of a person with it. They can’t help but get attracted to children. And under no circumstances that can be fulfilled legally, because to do so is committing statutory rape. Children can’t consent. This distinction is very important because (a) not all pedophiles sexually assault children and not all child sexual assault perpetrators are pedophiles; and (b) pedophiles who know that acting on it is wrong get little outside help.
