You can't shield someone from their own actions. I read about that in the Bible. You can try to tell them, warn them, beg them, even slap them, but they'll still do what they want. You won't take away their free will, so there's no way to stop them.

It's a real pain — really freaking annoying — but we gotta sit back and watch someone mess up sometimes.
