Bad means someone who would molest a child because it's a new experience or run over a stranger with a car. A business owner who is proud that the people he hires don't make enough money to eat.
Hitmen who consider the people they kill as rats so they don't get emotional scarred by the murder - they're in the 80%. A tyrant who orders a city pillaged and raped to assert dominance, also in the 80%.
Also, be careful how you assign "bad". It can either be unethical or illegal, as they are not the same thing.
