Do you think it is right to use violence to defend your family? Is it right to attack someone who threatens your family's safety? Why? What does it depend on?

It is always just to defend the innocent. If someone threatens the ones you love it is irresponsible if you don't do everything in your power to stop them.

We are biologically programmed as animals to protect ourselves and our families with whatever means possible when we/they are threatened. While I typically do not condone violence, under certain circumstances, I could validate using violence in defense of someone I love.
