Usage

What are other ways to say bad?

When describing things that are lacking in moral qualities or are actually vicious and reprehensible, bad is the broadest and simplest term: a bad man; bad habits. Evil applies to that which violates or leads to the violation of moral law: evil practices. Ill now appears mainly in certain fixed expressions, with a milder implication than that in evil: ill will; ill-natured. Wicked implies willful and determined doing of what is very wrong: a wicked plan.
