if you're talking deaths caused by capitalism vs communism they've both had flaws. like you're not taking into account of the amount of people sold and born into slavery (the number is incomplete but is upwards of 15 million), the great depression, WW2 (70 million). then the cold war (with the goal to spread capitalism). then the Vietnam war (2.5 million). then the chinese civil war (which the US and Russia fought in) about 10 million. Saying that communism kills and ruins everything is making it seem like capitalism is perfect but it isn't. capitalism killed millions, communism killed millions, but totalism kills more and takes away freedom of thought and conditions people to become almost robots.
