IDK

I need feedback. My older sibling has low emotional intelligence. Because of this they are unable to control their emotions, get offended easily, can never be wrong in an argument, and can't take constructive feedback or criticism. This on its own wouldn't be bad, but it's, sadly, not the only thing. Whenever they get mad they also get violent. They'll punch things or throw things around the house without a care for the damage their causing. If it's not an object, it'll be the person they're fighting with. (One time they took a bag full of nail polish and slammed it into my other sibling's head, who was trying to de-escalate the problem between me and my older sibling, for no reason other then that they were told to back off). This low EQ of their's is making it impossible to communicate with them. I can't even try and point it out to them in fear of getting into a fight I'm not ready to deal with. It's come to a point where I can't see them as a part of my life in the future and wish they wouldn't be. I also fear for the partner or kids they'll eventually have because, I can say for a fact that, there will be problems if they don't get help.
