I have a similar sentiment to the last one, where I view hatred as necessary to protect what I love when what I love is threatened. I also have a very strong ironclad rule against using violence on my loved ones, and only turning my violence against what threatens my loved ones.
This is one of many principles that I intend to impress on my future sons one day because I firmly believe that a man should never harm his family, and only use violence to protect his family.
