Rather difficult topic. On one hand it's like the movie Shallow Hal where near the end he's upset that he had been awoken from Tony Robbins spell which had made Jack Black (the lead character Hal) only see inner beauty.
The character Hal eludes to the fact that it would have been better to stay under this spell than realizing the, although very beautiful inwardly Gwyneth Paltrow (lead female character Rosemary), love of his life was rather obese and not the 10 as he perceived.
I've gone round and round on this one. In the end I come to one very important conclusion. It's good til it's bad. What I mean by that is the spell you're unknowingly under can seem or even be happy or joyous until there's some event that chips away at this perceived happiness.
What's the event? A loved one is treated harshly or even disfellowshipped. A major injury or illness strikes and your very life is at stake as you must refuse blood . You child is in danger and the mishandling by the body and the organization leave a very poor taste in your mouth.
These things suddenly make the spell you're under not so nice and on top of it the guilt that it puts on you may cause you to make a decision that could put your child's future at risk or worse yet his or yours at the risk of losing life.
As such if this spell is broken, when these serious matters arise the guilt is lessened at the very least and you may actually save someone's life...literally.
Although I don't think cramming tings down someone's neck is the correct approach, being honest and direct is. At a minimum it may cause the person to make a more reasonable decision than a hard and fast one that lacks direct biblical support.
