Fun fact - in the comics Forge made a gun that strips away mutant powers, and the government tried to use in on Rogue (which, having absorbed Ms. Marvel, was much more of a threat than her version in the Fox movies) - but Storm, ignorant to the gun's purpose, took the bullet for her. After that, lamenting the loss of her powers became her entire personality for a while. Comics being comics eventually she got them back - but I think that she is still a bit salty about this, and it shows in that scene.
We look at mutants and see cool powers, but mutants in the Marvel universe are first and foremost a hated minority. Storm wants to fight the very idea of the cure, because if the cure exists - mutants will be forced to take it. The poster boy of the cure in that movie was was Warren Worthington III, and he got one of the relatively good mutations (yes, it's physically visible, but it's not one of the grotesque ones) but his father still tried to force the cure on him.
It sucks for mutants like Rogue who really do want to get rid of their powers, but mutantkind as a whole does not have the luxury of allowing the cure to exist.
Nah, there is nothing wrong with Rogue. She just lives in a world where her evolutionary trait is frowned upon by society. If she was allowed to embrace her true self and kill indiscriminately she would be much happier. Even more so than giving up her genetic advantage.
It might be lonely for a time but we all know she eventually runs into someone who can neutralize her power.
Edit: looking online Rogue also gains full control over her powers in some instances.
i thought she just stole the powers of people she touched, and didn't kill them instantly with death touch?
in any case, she can steal the powers of mutants, which is a pretty good bonus ability to have on deck at any given time. tactically, to ensure the survival of future mutants that might get killed/cured, it would be better if, instead of getting cured, rogue just wore fucking gloves. you know, like what she does already. sort of the reason you might want mutants in the first place is cause like, sure, you get a random kid that gets born, and oh no, that kid kills everyone with super extremely toxic nuclear radiation in this super edgy comic where wolverine has to kill him, instead of just like putting the kid in a zero-waste nuclear power plant or whatever. or like a suit. you get that, but occasionally you also get somebody like forge, who can construct fucking insane technology, occasionally you get someone like prof. x, who has omega cranium dome, and can use the internet with his brain.
oh, but then, forge's technology is too dangerous, so we gotta cure him, and prof. x can read everyone's mind, so we gotta cure him so he doesn't see that i'm into freaky porn that will cause him to clutch his head and go "AUUUGHHHHH" and then faint, as is the fate of every psychic.
basically all that I'm saying is that this kind of mirrors exactly the same way that we look at neurodivergence or disability in real life. everyone's like, oh, we need to cure the neurodivergence with insane medication, or gene therapy, and the disabled people should be walking around on crazy robot legs! but then the robot legs were too heavy, and the anchor points that were directly mounted to your bones were super uncomfortable, and since people's body composition changes over time, the robot legs don't fit anymore, so you gotta buy another specialty production 50,000 dollar pair since it's not a mass production market, and, oop, since you're only moving around with robot legs and using 5% of your body in your thighs to work out, now you're fucked, instead of being jacked, like you would if you used a wheelchair. and oops, look like the robot legs have shit battery life.
and then realistically all of what people in wheelchairs wanted to be able to do was to like, use the bathroom effectively.
i'm not making the kind of blanket statement that, say, curing someone who's got such mental illness that they're nigh catatonic, is bad, they might thank you for that, right? but then i'd also say, you know, be careful at trying to "cure" everything, cause oftentimes the cure is some false solution, and oftentimes people really just needed you to have like an iota of empathy and understanding for their situation, so you could work out an actual solution for them, and what they need, and want. realistically you can "cure" a lot of things by just doing something really pretty simple and basically acknowledges the fact that some kind of people fucking exists at all. oh no! i have mental illness! maybe I should just be allowed to fucking exist, though, maybe i only have mental illness because we live in a society and i am the joker. bottom text.
