You do realize the context that the Pope was speaking off here were survivors of that Charter flight that killed 71 passengers right? In that context he is comforting the survivors. 

Also.....I highly doubt Machiavelli would embrace Liberation theology, the Preferential Option for the Poor or social justice for the oppressed because he believes right is determined by might. The failures of the Papal Commission on abuse has to do with the constant obstruction he has faced combined with the magnitude of the problem he faces. Marie Collins who resigned from the commission said herself it's wrong to say that everything is his fault.
