Originally, she was meant to be the 'Anti-Twilight Sparkle', broadly similar in capabilities and skill-set but with opposite alignment. As with lots of similar characters in various shows, she was popular enough that the decision was made to make her redemption a 'thing' and make her part of the main cast for the continuity.

I find myself wondering when the decision was made to turn her human equivalent into Starlight Glimmer...? No! Bad Ben! Sorry, I'm letting my headcanon take over there.
