If someone wants to feel helpless, then, uh, its not a bad thing.
If someone does not (most people in most cases, even people who do in some cases in most cases do not...) and you force that on them its very stressful and then quickly very traumatic. It is VERY abusive!
Another thing is setting. A game where someone can say "enough!" with trust and a desire to have fun, versus an institution where you have no rights, no ability to say STOP, and the whole point is to make you break, well, yeah.
I'm frankly just amazed why people don't ever think about what it would be like to go through it themselves? BAM - perfect litmus test.
