"The Church needs to cleanse itself by using him as the sacrifical [sic] goat on the altar of Justice!"

Ah, the classic 'two wrongs make a right' theory of justice. You don't like Cardinal Pell's conservatism, so he should be a 'sacrificial goat.' Never mind whether or not he actually did the crime.

Cardinal Pell needs to be taken down if -- and only if -- the court finds him guilty of the charges against him. Punishing him just because you disagree with his ecclesiology would be a monstrous miscarriage of justice, and there have already been far too many of those.

If he's guilty he should be punished. If he's not, he should be exonerated. That's the long and the short of it.
