This also explains why POTUS is so close with his family. There are so many you can't trust and the higher you go, the less honest and good people there are. No wonder he likes spending time with the "regular" people.
There's an old saying "You lie down with dogs, you get fleas". I think Cohen found himself in the ultimate position of being caught between a rock and a hard place. I believe he worked in circles of unsavory characters and left himself open to blackmail. He might not have even wanted to betray Trump(he could have made up even worse….and may still behind closed doors tomorrow), but he tried to work out the best deal for himself with the least prison time. I understand his attorney Lanny Davis(Hillary's attorney also) wrote his opening and closing statements which neatly laid out the MSM's narrative and talking points. In a weird way, Cohen cleared Trump for the most part.
So true. Rationalization has brought down many a career.
