Huggy, your statement "They saw it from Americans and therefore Americans made them do it" is nonsense. Just because there was a fringe eugenics movement in the US does not mean you can blame what Nazis did on Americans. I mean, then you can say that Americans are innocent because they saw eugenics from the Vikings and Spartans who killed newborns that they thought were weak.
teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"
