It shows the sheer hypocrisy of those who preach Christian values, then undertake acts they decry as sins.
I don't believe in any religion, nor any form of afterlife. But it would obviously be fitting for these evil scum (and all the other thousands of child-abusing priests, nuns and church people) to rock up to St Peter, gives them a huge crack round the head and banishes them to spend eternity in hell.
