An espionage organization is a collector: it collects raw information. That gets processed by a machinery that is supposed to resolve its reliability, and to present a finished product.
The difficulties of conducting espionage against the Soviet Union in the Soviet Union were such that historically the Agency had backed away from the task.
I could have stopped it after they paid me the $50,000. I wouldn't even have had to go on to do more than I already had: just the double agents' names that I gave.
When Reagan was elected, I felt that the Agency had gone much more into the service of a political tendency in the country with which I had already felt very strong disagreement.
When I handed over the names and compromised so many CIA agents in the Soviet Union, I had come to the conclusion that the loss of these sources to the U.S. would not compromise significant national defense, political, diplomatic interests.
When I got the money, the whole burden descended on me, and the realization of what I had done. And it led me then to make the further step, a change of loyalties.
There are so many things a large intelligence espionage organization can do to justify its existence, that people can get promotions for, because it could result in results.
The Soviet Union did not achieve victory over the West, so was my information inadequate to help them to victory, or did it play no particular role in their failure to achieve victory?
You might as well ask why a middle-aged man with no criminal record might put a paper bag over his head and rob a bank. I acted out of personal desperation.
To the extent that I considered the personal burden of harming the people who had trusted me, plus the Agency, or the United States, I wasn't processing that.
