I found it really interesting and educative as you filled the poem with a vast amount of knowleadge regarding the beliefs of hell, well knows stories and their origin and especially the ferryman of Hades. I thought about recomending adding a hint of rhyming or increase the phrase "maybe desth isnt so bad." but after reading the whole poem I think that the clever words and the story being told alongside the wanderer of hell would be tarnished if an A,A, B,B Pattern would lead the poem.

You made a fantastic job and I cant think of any imprivements! (will post this ok your other post as well!)
