Communists in the USSR (and backed by the USSR) stole property on a vast scale and murdered or enslaved people by the millions. The CIA did many bad things but it is very hard to out-do the USSR on evil acts.
West vs East Germany was as good an experiment as anyone is likely to ever see. It was capitalism vs communism head-to-head. The communists had to build a wall to keep their enslaved population from escaping from a secret police controlled hellscape to what was (in comparison) a capitalist utopia.
The US is a fundamentally mercantile country that found out the hard way (through two world wars) that non-interference doesn't work. It very reluctantly adopted the role of world police.
In many ways it resembles the problems all policing forces face, which is that people tend to focus on the mistakes rather than the successes.
The people that spend time railing against US policing failures spend no time trumpeting its great many successes.
It's always easy to point the finger. It's much harder to explain how one would have done a better job solving such complex problems.
