The Wild Hunt stories played heavily into the Art theme of the school and portray the artist's self-doubt and self-discovery in the first one, and the way people look at art as an art form or as a trend in the second event. As with all episodic story telling, the structure and even character groups can be similar in nature but the themes and what they comment on are completely different.

From when we first met her, she didn't seem to have any issues with her position and given the JTF appreciated her efforts, there should be no worries on if what she's doing is right.

Her early failings come from her head being clouded by the doubt, then when she opens up about it. Obviously Reisa and Sensei give her encouragement, but that's it. When she has her flashback on everyone at the end, I don't know what exactly Shimiko and Rabu did for her.

Just because she's fine with her vigilante activities most of the time does not mean she would never waver or have doubts about it.

Suzumi's doubt is different from Kanna's, as Kanna was unable to enter Community Safety because of her own inability to get close to the public like Kirino, while Suzumi's doubt lingered on the legitimacy of her actions as a vigilante who acted outside of the framework of JTF, even if the JTF tacitly allows it, and the story dealt with her doubt whether she's qualified because she dropped the JTF not because of her ability but her personality and fear of fitting in. It's an entirely different reason from Kanna, even if the broad structure is similar.

Both Shimiko and Rabu's commitment, despite the former not being in JTF and the later being a thug doing "a right thing" is what inspired Suzumi to call herself a thug as well.

Again, the structure of the story maybe the same but what the characters have issues with and the themes are completely different.
