Yeah, the Germans were systematic and that makes them worst. Thanks for answering, I was asking sincerely. Pretty much agreed on the comment that said that it was like asking if its worst to get stabbed in the right or left lung. Now I see the oversimplification, since in one case we have that "effectiveness" trait.

In any case, bwfore doing any ranking one should ask "why" do it... Like, what's the aim here.

But, since we are doing it, let me bring the case of Latin America. The royalty of both Spain and Portugal are to be scrutinized. If not for their systematic approaches, let's just try comparing the numbers. Entire civilizations were decimated. And the years it took were long enough to have settlers perpetuating actions locally... Oh, the cheery on top of it all is that until recently this wasn't acknowledged even at schools. Even today there are statues of f*ing Columbus in Spain. Or museums with weapons of 'Conquistadores' without really stopping to reflect upon the terror they brought to natives. And not so long ago, in Latin América, 12th Oct. was a holiday for commemorating the "discovery" of the continent... Just plain as that. Obscene and insidious genocide. For me, it's at the top.

Once, I read that Nazism is the internalization within Europe of Colonialist practices, only modernized (e.g. gas chambers vs. contagious blankets). Mindblowin' eh?
