Is OTHER wrong in the post ? POST : My mother has brought to my attention lately that things at her house have been pretty bad. My sister moved back in over the summer, after mom kicked her out previously. From what I was told, things were going great with her and she even decided to go to counseling, per mom's request. 

Every year, my step-dad goes to get a tree around December 15th. Not a big deal, right? Well, once sister found out, she confronted him about them planning things without her and trying to ruin her Christmas with her kids. Mom said sister came into her room and was yelling at her about never including her. Mom said she heard what sounded like a hit coming from the living room, so she got up to check. When she walked in, sister had hit step-dad. Mom says she attacked sister and started hitting her as hard as she could. Mom blacked out, from texts later sent. Nephews were yelling at sister "Mom, stop. Stop hitting."

Next day, mom cuts sister's phone off. Sister starts walking down the halls, banging on the door every time she walked past. Yelling out "Does your husband know you're fucking ----" "I'm going to call immigration" 

After then, she's been sweet to mom. 

Mom has been having mental health issues, called her counselor and told them things like "I just want to get in bed and sleep forever" Her mental health facility told her if she didn't get to their office within 15 minutes, they would be calling police and ambulance since it is a threat of self harm.

Few days later, mom says that sister was getting ready to go out after mom told her she wasn't going to babysit. When mom called sister into her room to tell her nephew #2 was hungry, sister insisted she was about to be picked up to leave. Mom was recording her, so sister tried to grab the phone. 

Now, mom is dealing with having to go to different counselors or go to the psychiatric ward. She's sleeping all the time, much like she did when I was in high school. 

She told me Friday she was thinking of calling CPS because she had to call the police on sister for the 2nd time. When the police were there, they said sister could go into whatever room she wanted. Then sister told police that there were two immigrants living there.

I told mom if she needed temporary custody of the kids, I would take them. I raised nephew #1 until he was about 2 or 3. He's now 10. 

Sister is on and off drugs, mom is in and out of depression. 

I am stable with a husband and child. I have messages and videos to prove I am fit to care for nephews.

So...am I the asshole?

TLDR: Mom and sister are crazy and I want to get custody of nephews.
