Nobody is above criticism, obviously.
But this rather begs the question: why on earth are you expending this much energy picking apart celebrities who were, by all accounts, decent, generous people who gave considerably more to the world than they ever took from it - seemingly just to rummage around for something, anything, to criticise?
What exactly is the objective here? Why is this considered a worthwhile use of your time when there are plenty of genuinely vile, damaging people in the world who actually do need to be held accountable? Wouldn’t directing your outrage towards people who have caused real harm be, you know, somewhat more productive?
I genuinely don't understand the obsession with finding fault in people as though uncovering some minor imperfection is a great “AHA! GOTCHA!” moment. Congratulations, I suppose: you have discovered that human beings are not perfect.
None of us are -including you, OP. I’m quite sure that if someone decided to go digging through your private life with the same level of forensic enthusiasm, they could find things to criticise too and parade your shortcomings around like some kind of negative Mardi Gras.
The fact that someone was fundamentally a good person doesn't require us to pretend they were flawless. It simply means that, on the grand scale of things, perhaps their flaws aren't the most pressing moral emergency of our time.
