Increasing freedom in the world decreases the death toll of its wars. Surely, whatever reduces and then finally ends the scourge of war in our histor… - Rudolph Rummel

I conclude that nobody can be trusted with unlimited power. The more power a regime has, the more likely people will be killed. This is a major reason for promoting freedom.

In a few cases, regimes have publicized their murders, often to intimidate people. For instance, Communist Chinese government newspapers would report speeches by officials in which one might boast, ‘We killed 2 million bandits in the 10th region between November and January.’ The term bandit was standard lingo for presumed counterrevolutionaries.

The more libertarian a state, the significantly less internal violence it has, and the significantly and predictably (in variance terms) lower its possible peak violence.
