Completely agree man. Tragedies like this can define the tone and world building of a series so much, it can really ground in reality for those oblivious to it.
As much as it breaks my heart to see Moria suffer like this, at the same time, his perserverance to never give up and keep trying, to adapt is extremely inspiring. He stayed true to himself and I think like many others who gave up on their dreams/ambitions, they are feeling resurged by encountering, fighting and being defeated by Luffy.
As much as he's defeating them and "ruining their ambitions", he's ironically saving them at the same time and realigning them to their true ambitions and selves. Like reginiting a long lost, extinguished flame or something like that, a phoenix rising from the ashes. How fitting for a Sun God lol.
Also on a certain other note relating to deep tragedy too....




I'm adamant we're gonna get Garling hunting down Shanks' mother during the slave hunt or she will die to someone else at least during it. But more likely Garling for maximum narrative sadism and thus tragedy from Oda.
One more hint from Redon btw:
