Differences Between Souichi Tomoe and Kaolinite

Hi, everybody, it me, Kimberly Jordan, famously known as Kimberly AJ, and I've been a fan of Sailor Moon for some of my years. I watched the original anime's 3rd season where a possibly assumed couple name Souici Tomoe and Kaolinite had their roles switched as main antagonist and secondary antagonist, compared to their manga. First, I would like to start with Kaolinite who seems to be the main antagonist of the original anime. So Kao, how did you become like this?

Kaolinite: Well, I seem to have a different story that differs between the anime and manga. I humbly confess that I blamed Hotaru Tomoe for the things she didn't do and it's not her fault, but mine.
