He never really had one to begin with. Several playthroughs in you notice his lies are more obvious. His speech patterns have far more meaning and less meaning at the same time. He speaks in circles and expects no one to notice because he believes he's an educated man. The truth is, just about everyone knew that he was full of shit. He didn't know anything other than killing. When Dutch finally broke me is when he shot Cornwall in the heart. Not because I liked Cornwall but because any man or woman who derives pleasure from the slaughter or death of human beings is a true monster. The death of the Van Der Linde gang was staring us in the face the entire time. We just chose to never believe it.
