There's a reliable economics to movie character deaths. If a heroic character is going out, you can bet it will be with plenty of slow-motion shots of his eyes looking to the heavens. Villains are more of a mixed bag. Hans Gruber snapped off enough clever one-liners to earn some extreme slow motion as he plummeted to his death, while the bad guys who tried to kill Vito Corleone in his hospital bed got coolly dispatched with a mouthful of pasta halfway down their throats. But occasionally, a movie chooses to kill completely innocent characters in the most horrible way possible for no discernible reason. For instance ...
5A Paralyzed Mutant -- X2
Like all X-Men movies and comics, X2: X-Men United is about what a bunch of assholes able-bodied humans can be to our differently abled mutant peers. And no character bears the brunt of our assholery more than Jason Stryker. His father is the movie's mutant-despising villain Col. William Stryker, who sends Jason to Professor X's school because he thinks it's one of those gay-to-straight conversion camps for curing people of their superpowers. When he learns that Professor X is teaching Jason to embrace his power (creating controlled hallucinations in people's minds), he blames himself for doing a terrible job researching the school and learns to love his son for what he is. Or that's what he would do if he wasn't the worst father in the world. In reality, he yanks Jason out of his self-actualizing environment, lobotomizes him and uses his son's brain as the joystick in his quest to destroy everyone who has the nerve to be disgustingly abled like him.
"Well, I might be biased, but I think that's the best Christmas card photo we've ever taken."
And that's before we even get to the fact that Jason's in a wheelchair, which is what the X-Men universe does when someone with telekinetic powers needs to seem more sympathetic.
OK, so Jason doesn't exactly pull off "sympathetic" so much as "Donnie Wahlberg's character in The Sixth Sense, as played by Crispin Glover." But you'd probably look a little washed out, too, if your Dad was using your brain to kill an entire race of people just because they remind him of you. Jason is a character who is built to be pitied, not hated. He's no more responsible for his actions than Master Chief is responsible for having worse aim when you're drunk.
As the climax closes in, Jason's dad is using his brain to trick Professor X into killing all the world's mutants. The X-Men figure out what's going on just in time, and Nightcrawler teleports to Professor X's side to find him sitting across from Jason in the belly of a crumbling dam.
"Thank goodness for the Protagonists With Disabilities Act, eh?"
Unfortunately for Jason, the dam is about to disintegrate and kill everyone in its general vicinity, he's in a wheelchair and he's spent the last hour helping his dad screw with the only people who could save him. Fortunately for Jason, there's a clear precedent for this sort of scenario that says you always take pity on the pathetic bad guy who's being taken advantage of. If you've seen The Goonies take pity on Sloth or The Karate Kid take mercy on Johnny Lawrence, you know that Nightcrawler's next move should be to lift Jason out of his wheelchair and tell him "It's not your fault" while a bear hug teleports them both to safety.
So what does Nightcrawler do?
Guys? Guys, it's not funny anymore.
Either because they forget that Jason is handicapped and therefore can't escape or even move, or because they just don't care, they just leave Jason to helplessly sit there as the entire dam collapses in on him.
It's not like they didn't have the time. A few minutes later, the X-Men are still escaping, and they take the time to offer to save the life of Jason's father -- the guy who was manipulating the mutant they just left to die. When Stryker tells them to go screw themselves, they just move on. The movie remembers to apply its core message of compassion for mutants and mankind to every single character except the most pathetic and helpless of them all.
But to be fair, he did have stupid hair, and he deserved to die for that.
