More or less, Scott is, at least in this era, a deeply heroic character who is forced to be a leader in situations he is just not equipped to deal with mainly because he is the only one who can. It gets noticed in the comics where he needs to train the team, and his mounting frustrations and grief interfere. He does acknowledge he is flawed and making mistakes though.
After this era.... Well I really hope Null is David Haller because that level of BS on the side of X-men would avert so much stupid and generally being a reasonable friend would avert far more whenever the Universe isn't bending itself to make everyone seem like they swallowed a gallon of powdered lead and mercury.
I'm probably just going to stick to the Chris Claremont era. It gets so dumb from there on after, and the latest comics are just outright offensive.
