I chose others because I do not feel that any of the choices would describe my thoughts about her. I actually think she should have refused to marry michael when he returned from sicily, but I think she was in love, and couldn't reason. But having taken the decision to marry a gangster, she should have been more adjusting, knowing well that michael wouldn't change. So my judgement of Kay is that she was immature and took a hasty decision. But she paid the price for it. Kay was somewhere in between a victim and a naive person.
