EXACTLY!! Not all Klingons could have been put into such a nice little box. Otherwise there would have never been engineers to develop their ships, no doctors, politicians, cooks or anything other than a "Warrior". To quote Worf from his speech to Alexander in First born: Every boy will grow to be a man but it is not certain that every man will grow to be a warrior Having Alexander there helped to show just how varied Klingons could be. ESPECIALLY when their upbringing was not the norm. Goes toward the nurture versus nature argument of raising children and how they turn out.
