I would go one step further by now- nearly all mental "disorders" make perfect sense as adaption to one or another state in a swinging habitat.

What we would declare a psychotic killer, is perfectly adaptet to a humanity locked into a state of constant strife. In such a world, actually not beeing a psychotic killer is "mentally sick" as in - bad adapted to the circumstances. As with all adaptions to circumstances, one trys to keep the circumstances optimal for ones own adaption. Meaning, someone adaptet to strife, will try to keep the environment stable, preventing the return of peacefull times- where they must subsist on institutional cruelty and torturing animals. Humanity is legacy hardware.
