It's not that 'having' willpower is bad, it's that the concept is misleading. Pretty much any story where someone changes themselves (or tries to) can be coerced into an anecdote about willpower. The point here is that the thing which decides whether or not someone succeeds at changing themselves is not the having/not having of willpower, it's everything else. And willpower as a concept is just one more distraction.
