Answer: Troubled leaders can have an unhealthy influence on their followers
Step-by-step explanation:
The possible theme based on the passage is that Troubled leaders can have an unhealthy influence on their followers.
From the story, Captain Ahab stood erect, and there was an infinity of firmest fortitude, and unsurrenderable wilfulness as he gazed over the ship's prow.
Due to the fact that the master was troubled, this had a negative effect on his followers too as they were uneasy as well.
