True, but also nothing to suggest any changes from canon, where we were also led to believe him evil until The Reveal. Well, there is the possibility that someone in Azkaban is thought to be Sirius but isn’t, which is a sign that Sirius may have imprisoned someone in his place, and that would be an evil act. But even if this is so (which it may not be), it may well be a justifiable act from the perspective of the Order of the Phoenix (for example, if Sirius imprisoned Peter in his place, and otherwise the characters are as in canon).
Edit: Add the potential justification involving Peter (which is not an idea original to me, BTW).
Is Sirius a Death Eater in this fic? In canon, he was thought to be one, but he never was.
About Sirius we only have the story from “Skeptical Wizard” (about Weasleys’ rat) and some mentions in the Azkaban—nothing to suggest he was good.
