"After all, crime is only a left-handed form of human endeavor"

In this quote, John Huston is suggesting that criminal activity is merely a different way of approaching life. He uses the phrase "left-handed kind" to indicate that it is not the conventional or accepted way of doing things. By using this contrast, Huston is highlighting the truth that criminal activity is often viewed as deviant or unethical habits. Nevertheless, he also suggests that it is still a type of human endeavor, suggesting that it is a natural part of humanity. This quote challenges the idea of criminal activity being naturally evil and rather presents it as a different viewpoint on accomplishing objectives or satisfying desires.
