You are right, our behaviours are shaped by the various kinds of society we found ourselves. But notwithstanding, we can change our behaviours and do the right thing at the right time and also be an agent of change in any society we found ourselves. If you find yourselve in a society where they do the wrong thing, you can stand out among them and always do the right thing.
