It was kind of retcon-ish, but they didn't give Luna a second chance in Luna Eclipse - they were unsure about her, despite the fact they gave her a welcoming party in the pilot. Either way, Celestia knew that Luna wasn't evil from the start, and wanted the ponies to save her, not kill her. Babs got  a second chance because it was an anti-bullying episode, and not giving her one would ruin the message. Trixie's was left open.

I can't really think of anyone else who got a second chance, unless where talking about all generations. I know in G1 (which is the generation where at least two villains died) seemed to make a habit of always having one of the servants turn good at the end.
