VeroniK I think we have read your post to the end and the people who have responded have listed some vices and the euphemisms we use to describe them. This question is very subjective, what one person or group considers a dreadful vice might be acceptable in another environment. You surely don't want us just to list drinking, smoking, gambling, sexual aberrations, larceny, murder, etc - sadly these vices are common in society in most parts of the world. I thought you were asking us to describe how we refer to these in our (i.e. UK) society by the use of euphemisms - perhaps I am wrong.
