He doesn't think he's done anything wrong.
He doesn't really believe his mate did anything wrong.
He thinks it's years ago and nobody needs to bring it up now.
He thinks anybody bringing it up is deliberately attacking him.
He thinks that it's done to attack The Church.
He thinks it's the machinations of one woman to usurp his God given power.
He's still pissed off that Paula Vennels has been 'picked on' and thinks it's all a conspiracy to get him and his mates.
He thinks he's God's appointed representative on Earth and is The Church.
The money's better this way.
He thinks if he sits it out, everything will blow over and he'll be able to continue because nobody else will go for the job.
He doesn't care about the victims because they probably made it up, probably deserved it and in any case, he's far too busy to trouble himself with the whimpering of some people from the past and a mere woman.
He's got an awful lot of paperwork shredding to do.
He's no different from his mate that he protected and doesn't want that to be discovered.
Take your pick.
