JWs say they are clean and pure and undefiled and not like the world but in reality there are those that do very evil things and they either have fallen through the cracks, have gotten disciplined or disfellowshipped.
We realize that just because a person says they are a Christian, it doesn't mean they will always act like one.
Regarding pedophiles, do you believe that JWs have a huge problem involving an infestation of pedos?
