I.... I'm having a hard time understanding why anyone would have a moral problem with that? It isn't even 100 active CIA agents who have nothing to do with Russia, apparently these agents actively damaged them.
These are agents who have materially harmed another nation, it isn't as if they have only been acting in a purely defensive capacity and working on the internal security of the US.
You raise a point that they weren't acting in a purely defensive capacity - for all we know, "did Russia harm" could mean they were a counterintelligence agent that successfully sounded the alarm on a Russian intelligence operation on US soil. From that perspective, wouldn't Russia be the aggressor now?
