My mistake. I think I confused it for that anime that's been causing some controversy lately, where the grown man has the body of a child.

As far as drawn media not victimizing anyone goes: based on what I've read about the issue of mental illness, it's harmful for a mentally ill individual to engage in activities which reinforces their pathologies. In the case of a paedophile, it seems like it would be harmful to reinforce the link between sexual desire and children by enabling their fantasies. I don't believe that any temporary relief that offers would offset the elevating risk of committing a violent offence by someone whose mental illness is worsening.
