What are the motifs in The Man with the Golden Gun by Ian Fleming?

The nature of murder is a reoccurring idea in the story. Repeatedly throughout Golden Gun, the author draws attention to a fundamental difference between Bond and Scaramanga and, by extension, Hendriks and the other investor/mobsters with whom Scaramanga associates). The former, narration suggests, kills with some moral and/or avenging purpose—Bond cannot, or at least feels reluctant to, kill without it. Scaramanga, on the other hand, kills for what seems to be a combination of selfish motivations—greed, power, or just plain fun.
