There is something I need to ask about my thesis statement. I know that I have to support my thesis statement with ideas but I do not know that which part of my thesis should be supported. Therefore I am really confused.

I underlined my thesis statement. My thesis statement is:

However, as a result of these moral and cultural concepts, the victorian era aristocracy was corrupted and they should have changed themselves. 

In my essay should I support the idea that the victorian era aristocracy was corrupted? Or should I support the idea that the victorian era aristocracy was corrupted because of these moral and cultural concepts such as hypocrisy, sexuality, bigotry, addiction to money, changes in the society, and over-industrialization?

I underlined my thesis statemnt.
