Sociopaths never realize when they're wrong, and in turn will never apologize for their actions. Lightning Dust knew full well she was endangering the other cadets and nearly killed five ponies, yet all she cared about was her cloud-clearing time. Fast forward to *The Washouts*, she still doesn't acknowledge the attempted ponyslaughter, and puts a *child* in danger just to get back at her rival. I feel that sort of callous disregard for others makes for an irredeemable character.
