You can condemn, or openly criticize, someone who is behaving inappropriately. If you are an animal rights activist, you would probably condemn someone for wearing fur.
Condemn originally comes, through Old French, from the Latin word condemnāre, "to sentence, condemn." You may see politicians condemn each other in political ads during a campaign in hopes of improving their chances of winning an election. You also might hear of a convict being "condemned to death." In this sense of the word, to condemn still carries on its Latin meaning of "to sentence."
