"You will burn in hell for it."
You lack the authority to make that judgement, so, I beg your pardon, but I'm not too terribly shaken by your faux religious pronouncement. Eugenics was drawn directly from Darwin, by Francis Galton, the so-called "Father Of Eugenics."
You're starting to get a tad shrill. Maybe you should take another break and revisit this, when your emotions are more in check?
The word was coined by Galton, but the practice has been around for thousands of years. Plato is the oldest source for its application to humans. It is still practiced everywhere, and even recommended by FReepers on a regular basis.
