If it IS in the DNA, wouldn’t it kind of work it’s way out of the gene pool in a few generations?

Well, if one believes in the Theory of Evolution and the Survival of the Fittest, this genetic trait does not make for survival of the human specie.
Could be a recessive trait that “hides” through many generations. Could even be a spontaneous mutation that arises from time to time if there’s an error at the right spot.
