Although a loving person with his loved ones, Desmond used to be distant and even domineering with other people around him. In his mind, only certain people were worthy of attention, and the rest fell into various categories depending on the circumstances. At worst, once Desmond considered someone a threat to himself or his family, that person was likely to drop off the face of the earth.
His manipulative personality and tendency to violence made Desmond a person who rarely engages in sincere personal relationships with the people around him.
For many years, Claire was the only person in the world with whom Desmond had any emotional attachment, and no matter how many women Desmond slept with, none of them meant anything to him.
