I want to lock my abusive disabled sister away
Why do you think she needs to be locked up?
She is always very rude to me without any good reason
I'm sorry she treats you like that.  You can't lock her up, however, just because she's mean.  Just avoid her instead!
I'm not going to put up with her. I want society to lock her away and never take her out.
You don't get to decide to jail people against their wills because you have a problem with them. If she is disabled you can be the one to leave the abusive situation and move on with your life. It is really hurtful to suggest someone else be denied their rights when no crime has been committed.
