I think it's easy to believe a narrative like this about someone generally disliked, but the reality about basically everyone is that we have good moments and bad moments. People that are famous are constantly being watched and evaluated.
Given the inevitability of those bad moments being observed and reported, I don't think it's a good foundation for evaluating someone's character. In this case, it's mostly useful for confirming an already negative point of view.
