because Moby-D*ck is a senseless creature that acts out of instinct
Explanation:
Starbuck was the Pequod's chief mate (the second in command), and he openly opposed Ahab's quest for revenge. He was more worried about returning home with his family than risking the ship and its crew due to a maniacal desire for revenge. He considered the white whale to be just a brute animal without intelligence.
