The CIA's mission is foreign intelligence meaning they operate outside the US. Since it sounds like you're not in the US, you are far more likely to be targeted by the CIA (still very unlikely unless you work for a government) than people living in the US.
Correction, it works to maintain the current status quo.
The problem I have is that with the same mindset I should be able to say that about GCHQ/MI5/MI6 (intelligence services of my own country) but I cannot in all good conscience support a lot of what they do.
It seems like they exist more to protect the interests of the landed elite, the wealthy, privileged and powerful than they do to protect the nation and its people. The latter is just misdirection.
This is not necessarily good for humanity.
I think there is definitely something to be said for the fact that if the CIA is doing this, then criminals are too - since the fine line between what the CIA does and what a criminal does is simply, a sheet of paper with someones signature on it.
Most of all, however, I think its very important that we continue to reveal these secrets. For those of us not living under the CIA's nefarious shadow, it is good to see them get their secrets revealed.
