Name a movie where a character got a fate they didn't deserve.

Prim in Mockingjay

Tom Robinson in To Kill a Mockingbird (and Jem, too)

Romeo and Juliette

Eddie Carr in The Lost World: Jurassic Park.

I always find myself screaming at the TV set when he gets killed. Plus, it was the fault of the film's other 'good guys' (save for Ian Malcolm, who tried to warn Sarah Harding and Nick Van Owen, that they were being idiots).

In fact, unfair fates is a recurring theme throughout the Jurassic Park films. I also feel bad for Zara in Jurassic World, especially since her fate is so prolonged, Ray Arnold (AKA Samuel L. Jackson) in the first Jurassic Park film, and the poor dude who runs to "Blockbuster Video" to get away from the T-Rex that has attacked San Diego.

The little girl at the beginning of The Lost World also has an undeserved nasty encounter, although we are told that she survived (probably with permanent physical scars and psychological trauma, that not even her rich parents are ever going to account for).

Gene Hackman in Unforgiven. He was building a house.

Newt and Bishop in Alien 3.

Still pisses me off!

Naomi Watts in Funny Games

While it made sense story-wise, I've always felt a lot of pity for how Jerry Black in The Pledge ended up.
