Input: Sorry, first time poster here, formatting, etc. (Maybe a little too long backstory?) 

So, as the title states, my extremely close friend of 13 years recently passed due to a school shooting, where she was specifically targeted by her ex. She had multiple other siblings, most of which are... A little overwhelming to say the least. 

She was the only one out of them that her mother could rely on to take care of the little ones, because her older sibling was/is taking drugs at school/a complete asshole to the other siblings and parents. The next youngest sibling after her is attention needy and is verbally toxic, and won't accept anybody else's opinion unless they agree with him. The others are incredibly immature for their age (even before the shooting) and are physical with guests and visitors to the point of insanity (constantly hitting, biting, etc.) 

After the shooting, their family and mine became incredibly close because of the circumstances, but when it came time to have friends, see movies, etc. I wanted nothing to do with them, because of how they acted and were talking in public. They were openly arguing with parents/cussing them out in front of others/being dicks in general, and yet my family still continued to entertain them because "they're going through a tough time, they need all the support and love they can get".

 It continued to piss me off when the siblings repeatedly asked for food (bought from restaurants) when we mentioned we were going, and my mother would never deny them, reinforcing this behavior. It got to the point where they were invading me and my siblings social plans with friends, all because they heard from others that we were doing activities/events. Still, I was forced to go along with it and my day would then be ruined, because of the way they acted towards my friends/relatives.

Now, it's been a few months since the incident, but they're continuing to be this way, and I finally put my foot down. I told them they couldn't act this way around my friends, because my friends would be miserable but bear it for the sake of my friendship with them, and I would be miserable as well. I still would see them/talk to their family, but they absolutely could not act like entitled little pricks who used the death of their sister to get unnecessary things like clothes/gifts/etc. (No, they weren't poor and they had a constant supply of food/clothes/shelter).

 AITA for doing this? I know that they needed somebody to talk to, be there for them, and comfort them during their time of loss, but them throwing the death of my best friend back in my face every time they want a new jacket is heartbreaking and infuriating. I've talked to other friends who also talk to this family, and they seem to be having the same problem.

Again, sorry for rambling. This has been going on for months and I'm sick and tired of people using deaths as an excuse for personal benefit.
