No one is unethical. Even Tony Soprano and Michael Corleone exercised ethics of sorts. Ethics are a code of morality, a system of moral principles that govern appropriate conduct. Simply put, ethics are taught, caught, and accepted. They're taught in childhood by family or a social circle. Later, they're caught by exposure to differing standards of behavior from teachers, peers, and workmates. However, they're not yours until they are accepted and internalized. It's never too late to inventory your personal ethics and alter whatever's lacking.
