[S04E14] "You don't deserve to be happy." House to Wilson.
"And yet I am. You?" Wilson to House

House treats the symptoms, but he doesn't treat the whole person. He doesn't even claim to. He often makes a clear point that he doesn't care. House likes medicine because he likes to solve puzzles, and what greater consequences can a puzzle have than a human life? But ultimately, even someone dying doesn't matter unless House can't figure out the puzzle.

So, if the above paragraph is true, then why does House go out of his way to kidnap a soap opera star he believes to be dying in order to save his life? Is it really because he can't stand the idea of not watching his soap? I don't think so; he even encourages angsty actor Evan Greer (Sex and the City's Jason Lewis) to quit if he's not happy... well, sort of. But, back to the question: If House doesn't care, then why bother? Because it's a puzzle he can see daily, right in front of him, and he has to solve it. Apparently he has made multiple calls about it, because the actor knows who House is, so House simply takes matters into his own hands because that is what House does. House lives a life without consequences.
