unanständig vs schlecht
bad
'schlecht' and 'unanständig' can both judge behavior negatively. 'schlecht' is more general and can simply mean that something is morally not okay. 'unanständig' is more specific: it is often about bad manners, broken rules of decency, or inappropriate, sometimes sexually suggestive, words or actions. If you are only saying generally that something is wrong or evil, 'schlecht' fits. If it is about behavior and decency, 'unanständig' is more precise.
unanständig
Bei der Feier machte sie einen unanständigen Witz, und alle wurden still.
At the party, she made an indecent joke, and everyone went quiet.
schlecht
