Adrienn has a very specific view of good, at least to me. Xe knows what's right and can often be a little too proud, to the point where xe can be stubborn even when proven wrong. And while that may be concerning, it's been shown that xe will use that stubbornness for good rather than bad. I find it incredibly unlikely that xe will ever turn out to be an evil character. Xe is inherently good and wants the best for people and especially pokemon, as seen with our first encounter with xem in Citae. Xe suspected that Radomus was abusing G.G., and xe thought it best to keep G.G. away from Radomus while xe was still under the belief that Radomus was abusive. Adrienn would never take sides with an organization that has been shown to mistreat pokemon (PULSE, locked up pokemon in Blacksteam, etc.).
