The truth is that CIA agents' job is to turn individuals who can provide something of value to the CIA. They use various methods to turn these resources, primarily relying on human weakness that can be exploited. That resource is then cultivated for the value it provides. That's it. The handler's job is to gain access, whether that be to information or other resources, through the resource. The handler's job is not to provide for the well-being of the resource or their family afterwards, that simply isn't how it works. That isn't how the US government works anywhere, based on my experience. [[ETA, except the VA, we do this for veterans]]
These people have a job to do, a mission, and that's what they're doing. That mission may not be palatable to you, but that is exactly what is going on here. This article, suggesting there is some duty to provide for resources after they've helped the CIA isn't how it works, at all. Any assertions or conjecture to the contrary displays a rather large lack of understanding about how work is prosecuted at the federal level, whether that be in the CIA or not.
