Yeah I saw that yesterday at the gym about Aretha, and indeed none of us are immune. Also, a cynical part of me wondered, "Why is this important compared to others' deaths, why one death is known the world over, figuratively, while a child who barely had a chance at life is killed brutally after starving nearly to death all his life?" I suppose eulogizing celebrities and what they stood for may help inspire people, but that's so complicated, due to many of us having idealism almost subconsciously, or at least some, while the reality falls from the ideals, cognitive dissonance sets in, maybe it's optimism bias, survival instinct, a coping mechanism.
I don't judge it as much as accept it's just there as part of our species, it's perhaps why people become parts of various fringe groups, they feel like they're an underdog or outcast (that's why I came here actually, at least some of the reason), or they identify with certain aspects of the person or group, I suppose same goes for celebrities. But it all seems terribly unfair and random, doesn't it?
