"Jackie wasn't mean in season 1"... except she was. "Shauna wasn't ever kind"... but also she was.
These conversations always seem to omit stuff to paint a certain picture. To imply Jackie's total innocence and goodness, because shes been unfairly reinvented in death by Shauna and the others (and she has! but that doesn't change the reality that she wasnt all good and kind).
Jackie was kind, she cared about the team. She was hard-working. She wanted the best for people. She gave Shauna the last of her food. She was kind to Misty where others weren't. They didn't tell her about the Allie plan, because they knew she wouldn't allow it. But she also let her insecurities make her cruel at times. She targets Nat in her jealousy, when Nats done nothing to her. She's dismissive of Shauna and lies to her, even if its not malicious. Her treatment of Travis is also pretty questionable.
Likewise, Shauna is kind. She's the first to offer comfort to those she believe needs it. Javi, Jackie, Tai, Lottie, Mari, etc. Its a long list. But there's also cruelty, because, whatever her reasons, she did something that she knew could deeply hurt the person she cared about most. She prioritised whatever it was sleeping with Jeff offered, over Jackie. Not just once, but multiple times.
You don't have to percieve Jackie as all good, just because she in some way stands in opposition to what Shauna's become. Jackie wasn't perfect, thats the point. The facade of perfection was a lie, and (as we see in the pilot) maintaining it weighed heavily on her. She was equal parts good and bad, like they all were in the beginning, and frankly i question the need to pretend she was more innately good than any of the rest of them. That was not what made Jackie singular. What made her different, was her not being afraid to stand in opposition to the new status quo. To openly reject the wilderness. To question it.
We don't need to rewrite who Jackie was and sanctify her. She was a normal, sometimes incredibly kind, sometimes spiteful, teenage girl, and her death doesn't become more or less tragic depending on her moral quality.
