I actually find it really useful for teaching kids, since there's an idea that anyone has good in them and can change. It helps them shift from saying "so and so is a bully" to "so and so, please don't hit me." Which helps so and so consider their behavior as a choice and not as an identity, and teaches the other kids to communicate their needs. I'm like, "remember how even Darth vader chose to be good? Anyone can do that, no matter what they've done in the past"
