The usual snare with which the devil catches the young is to fill them with shame when they are about to confess their sins. When he pushes them to commit sins, he removes all shame, as if there were nothing wrong with it, but when they are going to confession, he returns that shame magnified and tries to convince them that the priest will be shocked by their sins and will no longer think well of them. Thus the devil tries to drive souls to the brink of eternal damnation. Oh, how many lads does Satan steal from God – sometimes forever – by this trick.
--St. John Bosco
