If evolution jumped to perfection
we would not have psychopaths and sociopaths
While you're on the right track -- a reminder to make this explicit:
Evolution is not a path to some arbitrary concept of perfection.
Evolution just is.
The human race, for example, is no more a pinnacle of achievement than the humble banana slug, or the amoeba.
Indeed, by another metric, one might well say the protists are doing better -- they've been around longer, and have more individuals in more environments.
Likewise, an arbitrary classification (psychological conditions) need not apply to evolution; it just is. Indeed, psychopathy and sociopathy have well known evolutionary functions; which is exactly why the rest of us hate them so much (reference the survival-of-society versus survivial-of-individual game-theory square).
Regarding lawyers, in principle, they swear to uphold ethics as well as the law. Law, in turn, is typically constructed from an ethical basis; but in practice, it is more realist than that. The laws that lawyers themselves must adhere to, are there for this reason: as a balance, if not a strict yes-and-no. Which is fitting, as law itself is a hazy yes-and-no argument when heard in court.
I assume blueskull is referring specifically to those lawyers in China, where the law bends much more heavily towards the realist side than the ethical side.
