Would you cut your sister off for this

My sister is one of the very few people who chooses to live off the government and not really work. She collects food stamps and gets housing assistance. She does make a lot of money though because she sells drugs. Not weed. Usually heavier stuff. My family excuses everything she does because she was molested when she was 4. I understand but she had medicaid. She could go to therapy if she wants. She has 6 kids, one lives with his dad and 2 are in the system and she hasn't even tried to get them back. My family has guilted me into feeling bad for her. Now my husband was an alcoholic and I have sympathy for alcoholics and addicts but she isn't on drugs. She just sells them. My husband is in a wheelchair right now because he was out jogging at night and a drug driver hit him. He's only been out of the hospital a week. He's in a lot of pain and he's on Percocet. My mom and my sister came over my house. I didn't mind because my mom was there with her. Well she stole my husband's Percocet. The reason is she took money from someone and promised them drugs and then gambled the money away and couldn't get any drugs for them. That's the last straw for me. I'm over her. You know your brother in law is in pain. Physical therapy kills him and you're gonna steal his meds because you gambled away money you were supposed to use for your shitty drugs. I told my mom and blocked my sister and my mom is guilting me. There has to be a point where you take responsibility for your own actions! My mom is also sick and she doesn't want to die knowing her daughter's aren't talking but I can't have her in my life anymore
