What is the moral climax of Huckleberry Finn?

Could you please elaborate on what you consider to be the moral climax of Huckleberry Finn? I'm curious about how you perceive the pivotal moment in the novel where Huck's moral compass is tested and he ultimately makes a decision that challenges societal norms. Specifically, how do you interpret the scene where Huck decides to help Jim, a runaway slave, despite the consequences it may bring? Do you believe this moment serves as a commentary on the broader themes of morality, freedom, and justice in the novel?
