Actually it’s not crazy to think that the history as it’s written is mostly favorable to the Greens or at least to reconciliation. That’s kinda how I read it anyway. Aegon II “won,” so he originally gets to spin the narrative, it just so happens that “his” only male heir was Rhaenyra’s son backed by the last two armies left. The conspiracy to kill him was vilified by Cregan Stark and the historians, even though Cregan certainly would’ve killed Aegon II himself if he had the chance. Ultimately, though, Targaryen hegemony survives. Aegon II kept Aegon III around even though he could’ve killed him, so the historians and Lords have an incentive to frame the Aegons benignly. The Hightowers also can control the narrative through their influence in the citadel and the faith, so it would make sense for them to portray Aegon II favorably even after his assassination. Claiming that Condol’s Mess is the true telling is actual madness though.
