The evil of child sexual abuse is not defined by the immediate reactions of the child. Even if the child does not immediately experience it as negative, intervention and healing is needed. We cannot defy our biology, which shows that our brains do not mature until late in adolescence, and we need mature brains to make reasoned choices from the options we are given.
Trauma from child sexual abuse presents itself in surprising ways. These ways are important to understand in order to help heal children. We appear to have a window of time in which to care for and heal children before their lives are ravaged by the sexual abuse they experienced.
