Yes, pretty much agree with this.
Also good people are good people and treated as such in this quadra, gammas usually don't just hate their enemies they also love their friends, loyalty is in high regard even though because of the subjective Nature of Fi- i have yet to see a (permanent) quarrel between gammas where not both sides tend to feel betrayed in one way or another.
Maybe this could be why gamma is so lonely, harsh jugdement with who is worth your time while every gamma has a a somewhat differing vision of what is the right standard of behavior.

A bit of topic: Gammas seem very rare to me too, i don't really meet that many of them tbh, it's a pity.
