Again, Obama could have very easily made an issue of the way the DNC treated him. Hell, he had absolutely no reason to reconcile with Clinton given her campaign had lobbed some particularly vicious attacks against him during the primary. But he did, because the alternative was needlessly causing a fracture at a time when the country needed to get the GOP out of office due to the economic crisis they created.
Rather than wait until the election had concluded to conduct a postmortem and campaign for reform of the DNC, the Bernie camp responded to similar treatment by raising all manner of hell while the general election was still going on, further damaging Clinton as a candidate relative to Trump and embroiling the DNC in entirely deferrable debates about reform at a time when it needed to be focusing on, you know, actually getting Democrats elected to office.
To use a D&D analogy, you aren't being Lawful Good by immediately resorting to combat at every sign of injustice. You're being Lawful Stupid.
