>sadistic and yandere
This will be a hard one to answer... So the rage and sadism is the last parts that keep us human. The last "survivor mechanisms". When you get to your "lowest point" 1 last rush of power will awaken and you will be able to fight off many things with that "Last stand". (This energy rush is so powerful extreme spiritual practices make use of it) Also a human evolutionary mechanism. Especially because if you don't use it as a self preservation mechanism but get "drunk" on the feeling you can destroy yourself in the process.
>do we do anything about them
Once they fulfill their objective they should leave. I couldn't get particular contracts that should make them kill people for no reason outside of "coercing you".

Also sorry but I don't know what they are making you go through because humans have built in survivor mechanisms and they are really hard to "shake off". Like most people who try to kill themselves fail at the first time. It just tells them don't do it and they change their mind. That mechanism works well and they have hard time overcoming that mechanism that you were granted when you became a human. They are trying to reduce every force they need to "fight" when they will take you away.
I don't know if they will be able to succeed. I cannot locate your "true nature" to tell you to get in touch with. It's too faint. It's kinda etheric and makes me think of the feeling of melancholy but in a nice way. Humans have powerful emotions and your sisters are trying hard to get hold of something that can rival it.
