Look at things from my point of view. All I want is to have a world where things happen a bit differently, a world where everything is made of opposites.
You could even look at it this way; All liars would become honest citizens, all destructive equines would lose that particular tendancy. Admittedly there are a few flaws in my plan. OK, maybe all the truthful ponies would become the new liars and we'd have a few more pyromaniacs and the like.
I like to think that it's a work in progress, so my next idea was to make sure that those ponies with destrucive tendancies were stripped of their magic for those unicorns.
A simple switch ey?
