What I interpret you saying is that descretion is the better part of valor. That may be in certain situations, but I believe in this case morality trumps wisdom. It may have been wise to ignore the deprivation of a child, but it wouldn't be moral.
Jesus said that who would give a child a stone when he asked for bread. It is incumbent to protect children, especially from Muslim perversions. If one doesn't, then one is no better than the perpetrator.
There is no act that makes the situation worse for the child here.
As for the pervert it would be better for him if he were fastened to a millstone and cast into the depths of the sea.
Beating him up is the worst of both worlds. You can BET that it has been taken out on the boy.
