The most pernicious logic of AL is that sometimes, due to the complexity of modern life, God invites you to remain in a state of mortal sin in order to do good so it is not considered a sacrilege if you use the Eucharist as some sort of medicine in the field hospital of life.  Notice how the sin of sacrilege, that sin against God, compounds the original sin of adultery, the weakness of the flesh?  Notice how the real presence of Jesus Christ in the Eucharist has been reduced to nothing more than medicine of questionable value without even a placebo effect.

In some parts of Canada, they're following the logic of AL to give the Viaticum (final communion) to people who have arranged for an assisted-suicide procedure.   They don't even bother with the pretense of field hospital medicine.  In San Diego, they're following the logic of AL to give the Eucharist to active homosexuals who can't be bothered to change their lifestyles, but they would like to use Eucharist as some kind of placebo.
