What Examples of bad morals?

Morals are a very subjective thing. Bad morals vary by culture. For example in the Roman Empire having a slave wasn't bad, but it is now. In Nazi Germany multiculturalism was bad, but now many if not most of the world enjoy the diversity in our culture. But there are some consants, we generally don't like the killing if innocents (who ever they may be), we don't like rape (what ever it definition is), and other things of that nature
