Rudy: When he tackles the guy in the final scene and they show his father, his brother, his freind and the groundskeeper guy and they're all proud of him. Made me
Stand By Me When Chris stands his ground and Ace was about to kill him, but Gordie shoots the gun off.
The War When Kevin Costner's character gives the cotton candy to those asshole kids, when his son(Elijah Wood) just got beat up by them.
Of Mice and Men When he shoots his brother. That was tough to watch.
