The most ruthless of the ostensibly "Christian" shabbos goyim (Trump is a good example, look at his children) are progressively married into the tribe. It's a positive feedback loop that only incorporates the most cunning, ruthless, and completely amoral into their genetic matrix. Anyone with a hint of a conscience or lack of in-group conformity is sacrificed, cast out, and/or doesn't reproduce. There is also the gene stealing for the purposes of aggressive mimicry, i.e. the history of jewish ottoman slavers spreading their demon seed into white slaves-concubines and illegitimates over the centuries. It's far more complicated than simple religion. Genetics and selecting for specific traits has been an essential element of their success.
