Dante's Prejudice

At first, when the class was discussing Dante and Ulysses, I thought Ulysses got what he deserved, but after further thought, Dante’s prejudice against Ulysses became more evident. It would make sense for Ulysses to be in Dante’s hell because he did things in life that were worth punishment. Dante, however, could have put Ulysses in his hell because Ulysses died a natural death later on in his life, but instead, Dante chose to kill Ulysses in order to put him in hell. Dante obviously felt some animosity towards Ulysses, the question that we do not know the answer to is “Why?” Also, I found an article that poses three important facts about the punishment that Dante chose for Ulysses. The article can be found at http://www.jstor.org/pss/477002 . Professor Stanford believes that Dante did not punish Ulysses for his last search. I think that the strongest argument for his theory is his number two reason: Ulysses was punished with Diomedes who had nothing to do with the last voyage. This theory raises more questions. If Ulysses punishment was not intended to be for the last voyage, then what was his punishment for? Why did Dante kill Ulysses? We can only speculate the answers to these questions, unless someday we meet Dante.
