About 20 million died in world war 1, and deaths were primarily combatants. World War 2 was directed primarily at killing unarmed. The Nazis wanted to colonize eastern Europe, so killed many to make room for that, as well as anyone that did not fit in with their notion of racial purity. The Japanese killed their millions in China, but also elsewhere. The Italian killing fields were in Ethiopia. The Soviets killed millions of prisoners of war. Looking at the ideologies of these countries, their goal was to kill anyone who got in the way of those ideologies.
