Jane Seymour on East of Eden

Oprah: In developing the character for the screen, you must have thought about [Cathy Ames] more than all of us who have read the book, about why she was the way she was. Do you have an answer?

Jane: I think she is totally sociopathic. I think she did it because she had that power. She just could. I think she had no human feelings. She had no sense of remorse. I think there are people in this world who don't have human feelings. They don't have emotion. When she shot Adam, it was cold-blooded.
