Our own Holocene mass extinction

Our brain, which is too big for our body, excessively exalts emotions. Simultaneously, it creates self-awareness, and self awareness ultimately leads to a hedonotropic behaviour, where pleasure seeking -i.e. the satisfaction of emotion- becomes the central motivation for action, not success. Is that why humanoid intelligence has never been developed before us - because it is a catch 22 unsustainable condition for an organism? After only about 200,000 years of existence, Homo sapiens has caused a mass extinction event that, if it continues at its current pace, is predicted to wipe out half of all species within the next century. Is that how the short story of Homo sapiens, error of evolution, is to end?
