In paragraph 5, what does Johnson suggest when he says it is "not a time for timid souls and trembling spirits"?

A unfair behavior

Explanation:

Iniquity is determined as the deviation from the situation which may be right. It refers to the gross injustice and the act of wickedness. The deed which is done or the actions which are taken are determined as unfair in nature and lacks the law or the rule of doing the work. It is used in the sentences for depicting the hostility of the actions so on and so forth. The option of unfair behaviour depicts the meaning of iniquity in this question.
