Explanation:
The text appears in Chapter 13 of the novel.
Billy Bud is a sailor and the protagonist of the novel.
The narrator in this text is referring to Claggart's passions. The narrator states that passions can bring a person to his lowest point and it does not require 'palatial stage' to be provoked. In this passage, Claggart had started to resent Billy.
Claggart is the exact opposite character of Billy. Billy, on the one hand, is innocent, Claggart on the other is evil and wicked.
