In my church we call this avoiding the near occassions of sin.
Some criminals, Christian or not, cannot get away from their evil desires.
If you were tempted to adulter, would staying away from temptation mean isolating yourself from all women?
Actually, I think we are meant to overcome temptation not isolate ourselves from the world.
No. Then again they are hardly comparable. Child molesters are deviant, their brains & right/wrong functions are warped. One cannot generalize & say they are ALL that way, but they seem to not change. The evil is carved in their psyche.
Often, from what I've seen, the molester will go out to do what they have done before. Adultery, while wrong, can be fixed if the soul is fixed. It is difficult, but possible. Child molesters and that ilk are different.
