I think you are underestimating pedophiles!
YES they would go through the indoctrination. This is an organisation who do the following
1. Allow children to be alone with adults who are not their parents - quite often in ministry situations and at parties
2. Teach children that the adults are their "uncles" and "aunties" and to trust JWs only
3. HIDE the evidence when abuse is accused! JWs is a religion where a pedo is more likely to get away with it even if the child does talk!
It happens outside the JWs but I don't doubt that pedos would join if they knew about this stuff.
