Okay...in Spider-Man, we thought the car jacker killed Uncle Ben, and so did Pete...they confronted eachother, and the car jacker trips, falls through a window and dies...so, now in Spider-Man 3, we know now that Flint Marko was the real killer...and it's also known that Peter forgives him...so, seeing how Spider-Man is a very noble hero, wouldn't he now feel sad that he let an innocent man die? Wouldn't that put some grief into the hero?
