Which villain drove Equestria closest to the brink of destruction?

[sourheartz 38]

i said tirek since he pretty much sucked the life out of everypony in equestria and, as celestia explained, the pegasi couldnt control the weather, meaning no rain, and the earth ponies were weak to the point where they couldnt tend the land, meaning no food. idk abt the unicorns though, lol  tirek destroyed equestria from the inside out in a way. im also just terrified of him so

Starlight.  Easy.  I mean, the dystopian futures we saw as a result of her timeline meddling were the worst state we've ever seen Equestria in.  If she hadn't chose to stop it herself, Equestria would have been gone.

Starlight Glimmer of course, I'm so proud of her, she is so cute! FiM teached me that you always have to forgive characters when they are more powerful than you and anypony else. And cute. The only punishment she got was to get rid of her former haircut. They were afraid to ask for more of her.

Discord because it's his fault that Chrysalis, Tirek, and Cozy Glow banned together and almost took over Equestria.
