The problem with these counts is there is no way of making them look good, like lives saved due to "x". How many people lived because the Soviets managed to eliminate all famines in their territory after that? A huge feat given their relative frequency beforehand.

What about blaming AK-47s? The police?
My point is that it's a pointless metric that is only used to drum up support against some group of people, not a useful one for objectively understanding anything. It does away with all context, and replaces it with some inane number.
