Heroes don't last forever. They eventually fall or show not-so-pleasant characteristics that turn people away from them. They Took a Level in Jerkass or fell much deeper into the realms of a Fallen Hero. But some people, and especially their closest allies, still have faith in them, even as enemies, regardless if they have fallen well behind their prime.
Someone who knew that person, or at least based on one's knowledge, would say how The Hero used to be a much better person. That person would usually go on like this whenever the Fallen Hero has hit rock bottom and is sucking the ground in defeat. Unlike "The Reason You Suck" Speech, which is used to belittle a target, this type of phrase reminds them of how they were respectable in the past and what accomplishments they made as an Ideal Hero. The Hero used to be a Knight in Shining Armor who fought for ideals, held moral values at heart, cared profoundly about humanity, or had some dignity that made great characteristics as a person. It doesn't matter what Start of Darkness they had, especially if they should not have surrendered to evil in the first place.
The speech is usually an attempt to make the target have a Heel Realization and the shock to come all at once. Shortly after recovering from this Heroic BSoD would one expect the Broken Pedestal to come back from despair, pulling a HeelFace Turn, and regaining the respect he or she once had. In some cases, however, they may ignore the epiphany instead and further indulge in misdeeds.
Can overlap with Villainous Ethics Decay, if one villain is saying it to another. Compare You Are Better Than You Think You Are and We Used to Be Friends. When someone decides to say Get A Hold Of Yourself Man, cue the trope. The Paragon Always Rebels, and is likely to be confronted for their fall in this manner afterward. What the Hell, Hero? is when this trope and "The Reason You Suck" Speech have a child together.
