Wikipedia has a slightly more balanced take on the "stealing Cuban children" story.

I'm not denying the CIA did horrible things. But just to be devils advocate: Yes, you can derive benefits from Nazi war criminals. In these cases, during that time period it was vital to know what the intentions and capabilities of the Soviet Block were. They did have expansionist intentions, and they even had plans to invade much of western Europe. That sometimes gets forgotten...

Most of the governments the CIA acted against have been much more "deranged and corrupt" than any US government. And you should be glad for this.
