The whole heading question is irrelevant. Because of Monsanto genetic engineering of our food, there's only going to be one more generation - plus, perhaps, a partial generation. Why? Because the GMOs are causing sterility among many of our young right now. See: http://www.nationofchange.org/monsanto-and-gmos-continue-make-us-sterile-while-infertility-business-booms-1370181154 and http://www.huffingtonpost.com/jeffrey-smith/genetically-modified-soy_b_544575.html. And Google: "Monsanto GMO sterility."

So you see? As the whole population will drastically decline in 2 or 3 decades from now, so that there isn't any reason to waste time on breeding out tyrants.
