While it is true that "reversed stupidity is not intelligence", that does not mean negative examples are without merits.
Someone once said to me "A smart person learns from their mistakes, a brilliant person learns from other people's mistakes."
Positive examples show you what you should do and how you should do it, but they often leave out why. A negative example makes it very clear why you should do things a certain way and avoid doing them other ways.
