Oh dear, I'm really surprised so many consider Worf to be a bad father, lol. I guess maybe this really says a lot about just how bad my father is, if I'd rather be Worf's child. For me because of my upbringing, I guess I'm really able to appreciate those things Worf did do for his son that would've really meant a lot to me, and I guess I sort of feel he started out as a very reluctant father but his journey ending in "Firstborn" was towards him realizing what a good father is, which is to accept your child as he or she is and not what you want them to be, which to me still makes Worf a great father in the end.
First, I am sorry your childhood wasn't what it should have been. You definitely deserved better.
What I am seeing in your post though goes more to the point of you feeling Worf was not as bad as your father, however, that does not equate to Worf being a "good" father either by human or Klingon standards. Worf's neglect made Alexander insecure, inept and resentful. Not to mention desperate to the point fool hardiness to try and get some affection and respect. Alexander eventually rights himself but I would say that had more to do with people other than his father.
