Dr. Hicks: Complicated
She's easy to admire because apparently she's rigidly honorable and dedicated to professionalism and thoughtful decisions rather than emotional ones. But she twice encourages Benton to stifle criticism of the morally questionable Vucelich, and her concern is not for medical research integrity but for personal and institutional reputation and grant money. She lies to Benton about Carter switching teams. She recruited Carter in S3/E13: "If Peter can't use your talents, my team can." Carter had made no mention of leaving for another team. And then she tells Benton in S3/E17, "Dr. Carter asked to be transferred to my team. You don't think I'd poach him, do you?" She absolutely poached him.
It's difficult to regard her in the same light after that.
