No they are not cured, just like an alcoholic is not cured. You can argue that statistics show that a sexual offender is less likely to relapse than an alcoholic, however placing that person in an environment where there is temptation is just irresponsible on both the offender and the people placing him there and are well aware of his background.But with all of that said ask yourself this, if you knew he was a pedophile, who "paid his debt" to society, would you allow him to coach your own children or your students?
