What made me stop and think about the guy's mental state is when he apologized to everyone at the agency that he couldn't say goodbye properly.
It's not like he went to prison. They can have a big party for him if they want.
But the truth is, he was let go for several reasons and everyone knows it. I don't see agents flocking to his side.
My take is that if he thinks he did something right, it makes it right. He’s got a loose screw.

As SE Mom pointed out these are things sociopaths say and the way they think.
