John's Selfishness

In Chapter IX, we saw John turn a complete blind eye to everything that he had back at home. He had the woman that he apparently loved for years, crying and begging him to help his home. Since the accident, John has become so disconnected from everything that he once knew. He left his first wife because she was becoming too old, and chased after a girl that was much younger than he. Reading the chapter, all I was thinking was, does this guy not remember anything from before the accident? Is he really that selfish to leave everyone that he once loved? Then, I came up with the answer. He never actually loved anyone. His relationship with Laurie was solely for himself. Sure, he has provided the world with unlimited power, and this could considered pretty selfless. However, what's to say that he didn't know what the outcome of this intervention would be? By the end of the chapter, however, I think John finally realized the extent of what was going on. I think he finally started to remember the person he was before the accident. I don't, however, want to come to a conclusion on John right now because he could end up going back to his selfish ways at the end of the book.
