I despise Worf. IMO the guy is a murderer twice over and has no place in Starfleet. Would Riker have gotten away with beaming over to a Klingon ship and killing a guy with a sword,no matter the provocation? Would Sisko or O'Brien get away with that whole blood transfusion fiasco? And please,that "alien culture/outlook" argument is the most morally bankrupt horse hockey I've ever heard.
