Bad choices make for great writing because sometimes the most foolish decision a character can make also leads to the greatest conflict that person will face. I know all of the great decisions my characters SHOULD make, and I'm going through my books right now and steering them away from those choices. Why? Because my characters don't get detoured enough by their bad choices. I need them to learn better lessons, make bigger mistakes, and generally ruin their lives to the point of near-destruction.
It's hard, though, because when I know what the RIGHT choice is, I always root for that decision. That just makes books boring.
