Will the questioner be sinful if she detests her father, who suffers from a mental illness, killed her mother, and she wishes to disown him?

Heartfelt emotions towards a father, such as disdain and hatred, are not held against a person. However, one must honor and be good to the father. It is not permissible to disown him or prevent him from returning home unless his presence poses a danger. In such a case, one can look for another place for him or allocate a separate space for him in the home, while still treating him well and providing for his needs. Likewise, a father does not have the right to prevent his daughter from marrying a suitable suitor without a legitimate شرعي reason.
