A potentially relevant excerpt from a 2014 article coauthored by Professor Martin:

"Finally, with regard to morality, aggressive humor appears to be the humor style that is most consistently (negatively) correlated with these variables. This finding is consistent with our expectations, and suggests that people who use humor to tease or manipulate others are less likely to define themselves by moral traits including fairness, kindness, and compassion. They are also less likely to respond in socially conventional and moral ways to scenarios placing a more moral response against a less moral option."
