I like this meme. I've addressed this topic before. The problem is that people suck at forgiveness. We like to feel self-righteous and angry. It makes us feel important (while at the same time simply revealing us to be petty and insecure).
Frankly, Mr Eastwood has done incredible things with filmmaking, and I hope that's how he is remembered. Even assholes can create great artworks, and the world needs more great artists.
