An Unbreakable Vow

[dooey100]

I've seen this concept in a number of books, some sort of promise that can't be broken, (usually due to magic). There are some variations, like the promiser dieing if they fail to do what they said, or being forced by some unknown power to either do it against their will, of have their will changed so they want to do it.

What I was wondering is: What would happen if there was something like this in real life? Would it be beneficial or not?

I think it would not be beneficial, I predict that it would encourage people to think: "Ha, he didn't make me promise with The Unbreakable Vow, that means I can do whatever I want."

Then people would begin using The Unbreakable Vow for all promises, knowing that that would be the only way the person would do what they promised. Which would essentially lead to the death of trust, because The Unbreakable Vow involves no trust, and no one would use "regular" promises anymore.


What do you think? Do you think there would be other benefits that outweigh these drawbacks? Or that things would not go as I think they would?
