What wicked activities do these people thrive on?

Les explains that these people thrive on the wicked activities Paul lists: envying, murders, drunkenness, and revelings. He notes that alcoholism fills prisons and the drug culture feeds in as well. He recalls a young medical intern who said the only place to make a lot of money is anything that will degrade society. Les teaches that reveling seems like a good time, but it invariably leads to misery, broken homes, broken health, and anything that breaks them. They continue in this lifestyle of the old Adam, which is the playground of Satan himself.
