One crazy chica

Ok so is Hedda jus mean in general, is she power thirsty, or is she bein mean in order to keep order in her life and her house. It surely does keep control over Tesman and Aunt Julie. It half way works with Lovborg until he notices she doesnt run him. But when she reached her last male figure, Judge Brack, it doesnt work anymore. Sho is she jus mean to people that she knows she can control or is it all for power until she reaches something that she can't control.
