Perhaps she knew that we would read her words, all of these centuries later, and see her for the bright, creative human being that she was. I hope she would take some solace knowing that we of the future see her condemnation as unjust, stupid and evil.
Its a nice thought, but I cant make myself believe it. It seems more likely to me that her words were coerced or forced and she was manipulated into confession. I imagine she was saying whatever she thought she needed to in the short term to appease her interrogators with no thought to future readers who had no power to save her. Poor woman.
