How do you deal with a deviant or destructive family or organizational culture?

I know this sounds like a depressing answer to the question of how to deal with a deviant or destructive family or organizational culture, but you can't change culture just like you can't change an individual's nature without a death or near-death experience. Both need to be changed from the inside out. So since we're talking about a culture, the only way to deal with it is to replace behaviors. When the people with the more constructive behavior outnumber the deviants, the culture will follow.”
