Thank you! One of the reasons I watch both movies almost every year is because I find something new, or see something in a different way almost every time. In many ways, Kay is the character that I despise the most.
Kay knew from the opening scene in the first movie EXACTLY what the Corleone family was capable of and she knew that Michael was a part of it when she married him. Then, knowing everything, she went along with the evil for years, but would still try to show moral outrage when it suited her.
