Replying to a dead comment that demanded an example, for example, Mao's mass killing of somewhere on the order of 30-40 million people famine (in addition to the million straight up murdered in the cultural revolution) created as a result of "helping" through planned economy food distribution and the Eliminate Sparrows Campaign.

People only kill at a truly massive scale because they believe they are doing something good or at least necessary (even in war, but especially outside of war). This is why hoping states aren't evil isn't sufficient-- in fact it may induce mass murder, because what could be less evil than to Do the Right thing.

The universal cure is to distribute power and influence in as many ways as practicable, such that the damage from erroneous thinking is contained.
