Why doesnt huck's conscience bother him when he lies so much?

Answer 1

Possibly because he's been lied to enough, that he figures it's the way of the world. People in his world tend to live on lies, half-truths and rationalization.

Answer 2

Huck has a strong sense of individual morality that is not based on societal norms. He lies for practical reasons, such as to protect himself and others, rather than out of malice or deceit. Additionally, Huck may not perceive lying as morally wrong in the same way as others due to his unconventional upbringing and experiences.
