Physically harming someone, including abusive parents, is generally not considered an acceptable or legal solution to address abuse. Violence is not an appropriate response to any situation, regardless of the circumstances.
If you or someone you know is experiencing abuse or violence, it's crucial to seek help from appropriate authorities and support systems. In many countries, there are laws and systems in place to protect individuals from abusive situations, and there are resources available to help victims.
If you are facing abuse or know someone who is, consider reaching out to law enforcement, child protective services (if the abuse involves minors), or local support organizations specializing in domestic violence and abuse. Remember, there are legal and non-violent avenues to address abuse and protect those who are affected.
