Well, she definitely isn't one of those goody two shoes reincarnated 'villainesses' who actually won't hurt a fly - while she isn't malicious for the sake of it, ultimately her priority is avoiding the bad end for herself, and then her friends' well-being. She even directly suggested using the system for covert intelligence gathering as an argument for its adoption. Basically her goal was to cause trouble to somehow derail the scenario, and hopefully get a bad reputation and avoid being engaged to the prince.wait a minute... the church becoming a bank... isn't that the premise of most evil churches that become greedy and corrupt leveraging their wealth to the local lords? so it's a evil church origin story that all started with a BL novel.
She might also need to release a new BL soon."I want all of us to live happily together in prosperity. To that end, first of all let's quickly make a bank."
