O'Brien and the conclave

There's a lot to read about the upcoming papal conclave at NCR ... Conclave 2013. Latest news is that Cardinal O'Brien, one of those who will vote in the conclave, has been accused by three priests and a former priest of sexual misconduct with them - Pope considering response to alleged 'inappropriate acts' by UK cardinal. As in the case of Cardinal Mahony, it appears that O'Brien will be allowed to vote in the conclave despite the allegations against him. One can't help but wonder what would be found out if the other 115 cardinals were looked at more closely. What bothers me the most is that the Vatican doesn't seem to give a fig about the ethics, or lack thereof, of church official, only about their loyalty.
