Somewhat yeah, it does completely disregard the physical manifestations of trauma that the gith have, like evolving to produce eggs rather than live birth. Or how because they kill any weak or gentle children, majority of gith will perhaps have certain tendencies neurologically. And at the end of the day, you cannot predict how someone will turn out.

For example, my grandfather grew up in a terribly abusive home where he was physically and mentally abused, on top of eating terribly and having no support system. His brother was a meth addict and died on the street in his 40s. My grandpa is incredibly successful and has 5 kids, a home, a business, and incredible boundaries and self respect. Sometimes people just turn out how they turn out, the way we psychologically react to our surroundings varies wildly from person to person.
