Mathew, Mark, Luke.....variously "It would be better to be thrown into the sea with a millstone around his neck than to cause harm to come to one of these little one"...
does seem the appropriate end for child molesters...

But Mr Vukovich decided to set himself up to be the administrator of justice, so he should heed John 8, "...then let he who is without sin cast the first stone..."

Mr Vukovich, you don't appear to be the appropriate party to mete out justice. We have a system of laws (flawed though it is) to protect the accused (and convicted) from the vigilante.

And even disallowing for all the above, Mr Vukovich actions were obviously premeditated (not in the heat of the moment or in immediate defense of an act against him), and his reasons clearly constructed to prey on our sympathies and help him avoid appropriate punishment.

Sorry Mr Vukovich, as much as I'd like to think they deserved it, your reasons for your actions doesn't pass the smell test.

Manipulate much...?
