There's always room for forgiveness, but that doesn't mean shrugging it off and acting like it didn't happen, or concealing it or denying it.
I can't see how there can be any possibility of anyone who has abused children being acceptable as a practising priest, or being trusted in any situation where he could do it again, or be tempted to do it again.
In fact that would be what any priest, or lay person for that matter, who repented what he had done, and might hope for forgiveness would insist on in any case.
And, as I understand it, after a period of shameful confusion, arising largely, I believe, out of genuine inability to believe that this kind of thing could happen, that is now the firm position of the church.
