Why do People Hate NK?

I have heard people relentlessly go off on Nicole K. So much so that it almost felt as though people were more upset with her than Chris, who confessed (multiple times). Why??? Why is SHE perceived as somehow equally as bad, if not worse? Is she bad because people are certain she was involved and got off easy OR is it because they perceive her as a homewrecker or destroyed a family (even though Chris was the one cheating)? Or both???
