My brother has autism and is a jerk. Will he ever change?

I definitely had/have some behaviors that make me *seem* like a jerk. Uncontrolled emotional outbursts, rejection sensitivity, a huge superiority complex, and just generally not knowing how to communicate. I might communicate "you seem tired, are you okay?" in terms of how it impacts *me* - ex. "you haven't been hanging out with me enough." Or, I might get frustrated trying to communicate to NT people and decide that they were "dumb"/not worth the effort. It's not something I grew out of, exactly, so much as I realized I couldn't function without those people and started actively trying to modify my behavior.

Although unlike other people in the comments I don’t think something else is going on. 13 year olds are just mean, amplified by the fact that he probably hasn’t always been held accountable for that. 😅

No he will not grow out of it unless he is taught out of it, jerkiness is usually a learned thing, my low empathy friends worked very hard to not be jerks! I babysat a kid like this, because of his autism nobody ever really taught him to not be a jerk and just let him do his own thing and now he’s pretty selfish and mean as he gets older. I know some of my peers who struggle find they have soft spots for some stuff, for one of them it’s old people and animals, for one it’s kids, for one it’s girls in general. Part of it is probably also just his age. 13 year olds are just…kinda mean…even if they don’t try to be kids that age are just kind of rude! You kinda learn the whole not to be a jerk thing around then

low empathy is an autistic trait but low empathy does not make someone a jerk. autistic ppl with low empathy can still have sympathy, and be kind and nice to others. sounds like your brother has something else going on.

This sounds more like something else. Autism does not cause people to act like that most of the time.

He will probably always be like this unless he and all the adults in his life, work with him to fix it. This probably has nothing to do with autism though, mostly with how he was raised to begin with. Even though autism is a spectrum and it causes people to act differently, most autistic people do know how to be kind or nice.
