Comparisons between Worf and B'elanna are difficult. It's not a simple matter of their interests. B'elanna was raised by a Klingon parent: her awareness of the culture should be more organic to her being. Worf was adopted by humans: in a sense he was a bookish Klingon. Indeed his sense of honor was more ideal than other Klingons. As for their tempers: Klingons displayed varying degrees of emotional control depending on their goals. Martok was far less impulsive than Gowron, less so that B'elanna, and perhaps less so than Worf.
