Both men feel guilty about withholding information from their companions. Odysseus withheld information about Scylla and the Charybdis for the sake of not losing all his men. He also withheld information about Aeolus in which he didn’t tell his companions what was in the bag that Aeolus gave to him. Krakauer kept the fact that some of the clients died because he didn’t want to discourage his other clients.
Both Odysseus and Krakauer experience survivor guilt when they lose their companions. Odysseus goes to the altar he prays and he cries. He goes to the gods.
