What about reviewing them and telling why they are bad. It happens that sometimes I play long sessions full of very poor games, and I have the feeling that something is wrong but I cannot tell what: what is the actual cause of such a mess? I believe that if we (consciously)know the bad moves we can avoid them and keep away the trouble they create. heres a first example i eventually spotted during some consistency practice: although having your 5th column raised is generally a good thing, raising the 6th column may be devastating !!

The purpose is not to tell some obvious silly stuff (eg "evil is bad") but to give clear a picture of what you should avoid (know your foe!),as conscious and sound knowledge seems more efficient than vague intuition here.
