Can you specify that David Mack meant that he thinks Janeway is a fundamentally arrogant character who deserved to die? Or is it possible that he viewed her death more as a tragic inevitability than something she "deserved?" Can you paraphrase what, specifically, he said, and can you say with confidence that he did not mean something else?
Why not just ask David Mack
? He frequents TrekLit on this BBS and I'm sure he would not mind clarifying the quoted material.
