Blind Loyalty Can Kill
There’s nobody on the show that was more loyal than Doug Stamper. He was the closest person to the Underwood’s, batting clean up when shit would go wrong or fixing loose ends that had the potential of turning into full blown AIDS. What did that get him, though? Like someone accused him of, he was just a glorified bitch for Frank Underwood.
Ultimately, everything he did for Frank, was way more than what Frank ever did for him.
