I feel like the running theme here with people's relationships (including Barriss, because that's hilarious) to Anakin can be summed up as below.
Obi-Wan: I could make him better.
Padme: I could accept him for who he is.
Ahsoka: I could poke him with a stick and throw peanuts at him.
Rex: I could help Ahsoka.
Cody: I could study him. Not sure for which field, but any of them is good.
Barriss: I could make him so much worse. *mild maniacal cackling*
Fox: I can point him at things and watch him kill the problem.
