To quote Ender&#x27;s Game: <i>&quot;I am not a happy man, Ender. Humanity does not ask us to be happy. It merely asks us to be brilliant on its behalf. Survival first, then happiness as we can manage it.&quot;</i><p>It doesn&#x27;t really answer why we commit suicide. But it does give an answer to why we aren&#x27;t happy.
