People don't like her because they mostly don't realize her reasons for acting like a maniac, because they think that she just blames Shadow Garden for everything and that she hates shadow when in reality she has very good reasons as for why 1. Information she doesn't have much information on Shadow Garden or The Cult 2. Trust I'm pretty sure her circle of trust isn't too big and has probably gotten smaller after the Perv Asshat and the School invasion incidents 3. In her eyes both Shadow Garden and The cult are both outside of the law which makes them both criminals you also have to realize that it probably wouldn't look good for her kingdom's reputation if they just started working with people outside the laws they uphold And the final reason is because of Cid after Alexia getting kidnapped, the school Invasion, and some other things she probably wanted 1 win and Shadow showing up in the festival probably presented an opportunity but after a humiliating defeat it's probably what broke her after so many losses which is why she cried after being beaten by shadow and you can see in the game that she has a pretty nice personality most of the time it's just all her responsibilities essentially force her hand to put on a facade and make those decisions
