As a lion, you should never fight with a mad dog.

The righteousness is: first of all, you have to understand that you are a lion and that evil person is a mad dog. A lion's opponent is never a mad dog. If you fight a mad dog, you will lose your status - think about it, would you be honored to defeat a mad dog? If you are bitten by a dog, not only will you be unlucky, but you will also have to recover from your injuries, which is not worth it.
