Katherine's lawyers are most likely to argue that she acted in self-defense in response to the threat of violence and that her actions were justified under the laws of self-defense. They may also argue that Katherine's actions were a result of her exercising her basic human right to defend herself against domestic violence and assert her women's rights to safety and protection. However, it will depend on the specific laws and regulations of the jurisdiction in which the case is being heard, as well as the specific circumstances of the case.
Katherine was just a example of several cases of domestic violence and harassment. In this case Katherine fought for herself and protected her from further torture.
Domestic violence is violent or aggressive behaviour within the home, typically involving the violent abuse of a spouse or partner.
Self-defense is a countermeasure that involves defending the health and well-being of oneself from harm. The use of the right of self-defense as a legal justification for the use of force in times of danger is available in many jurisdictions.
To exercise domestic violence on women at home is a punishable offence and one should be punished for the same, and women should take legal actions to protect herself.
