Measure for measure, the cardinal should go
Not reporting child abuse to the gardaí because of some canon law is not an excuse that can override the serious nature of his action. He must have known or felt that, surely? I like to think that all actions can be explained if we could but understand the mind of the “actor”.
If I was playing him as an actor in some film, for example, how would I enter into his head and convince myself that my actions were just. Moving a paedophile about and allowing him to carry on working and then not reporting his crimes to the gardaí ... how do you justify those actions in your head? It’s a headache even trying.
