My problem with Eugenics is that some of those "human specimens" were the ones practicing Eugenics and deciding who should live and die based on things like race and ethnicity and certain birth defects. People used Eugenics to play God with the species, and we lost some really good folks to people who, like Hitler, considered themselves "Eugenicists." It's extremely dangerous territory that destroys human potential, both positive and negative. I'd rather not.
