No, the definition of "ethics" is "moral principles that govern a person's behaviour or the conducting of an activity."

If you feel compelled to resort to immoral behavior to win arguments, you already lost, and your contributions to society are a net negative.

Your argument is like stating that ethics in life are meant to be the definer of how far to go in that cause, with police departments being the ultimate decider if you've crossed the line. However, if you rob and murder random people without being caught by the police, you are undoubtedly an utter failure in life.
