Lamo says that he feared that his family would be attacked if he didn't give away the information, that the feds would find out about his knowledge and conduct reprisals against his family.
"At the moment he gave me the information, it was basically a suicide pact."
"I was worried for my family - that if I were obstructing justice that they could be caught up in any investigation," he said.
"I wanted to do this one by the book, by the numbers. I didn't want any more FBI agents knocking at the door."
When you see the brutality of the Collatoral Murder video, you see the kind of evil involved, I can understand his fear.
BBC report on this...
According to Wired, Manning contacted Lamo after seeing that recent interview, claimed to feel him to be a "kindred spirit". Could Manning have Asperger Syndrome perhaps?
In the end, we're talking about a brutal regime, a brutal empire that will stop at nothing to maintain power.
"I want to be proud of it but I can't bring myself to be. I keep thinking about what it was like being 22, alone and not knowing about my future," said Mr Lamo.
"Knowing that I did that to somebody - it hurts. I feel like I should be talking to a priest."
He said he had been placed in a situation where "an impossible decision had to be made".
"I hope that Manning gets the same chance as I did - the same chance to take his punishment as I did and start a new life as I did."
"I like to think I prevented him from getting into more serious trouble."
