If some one wants to spoil his family or community.
But I am sure you agree with me that if some one is raised in an environment where there are no values like the wife can go with who ever man she wants then this will be normal because this is his environment.
For example in Europe people can go the Suna naked, they are used to it.
But here no, it is considered shame if we see some one naked in the steam bath room for example.
At the end it is all about what do you consider good values and which weighs more for you, is good manners more or bad manners.
