Ahab, despite his thirst for vengence he isn't a bad guy. He rewards his crew with gold should they provide valuable info on Moby Dick, and shares drinks with his men, even Ishmael depsite only knowing him for a few seconds. Is it really a wonder how he was able to talk Starbuck out of shooting him before he even finds out he was about to, or that his crew would rally on his side from his words alone?
Queequeg and Ishmael's entire relationship. From the time that they become friends, they always have each others' backs, no matter how dangerous like on the Pequod becomes.
