In "Cloud Atlas" by David Mitchell, a thought-provoking quote illustrates the consequences of unchecked self-interest. It suggests that if society continues to prioritize individual gain over communal well-being, it will ultimately lead to self-destruction. The phrase implies that predatory behavior will inevitably consume humanity, leaving only the most selfish in a world that collapses under its own excess.

Moreover, selfishness is described not only as detrimental to one's character but as a threat to humanity's survival. When individuals act solely for their own benefit, they contribute to the degradation of society and ultimately risk leading the species to extinction. This theme underscores the importance of collective responsibility and compassion in ensuring a sustainable future.
