Wouldn't call an evil pt a route for minority, considering the Dark Urge was one of the featured highlights of the late marketing (Blood in Baldur's Gate and the last pannel from Hell).
It is. Larian themselves even said so. They mentioned they focused on Good route because very few people interact with the Evil route.
The Durge has nothing to do with the Evil route, since it can be (And most often is) taken through the Good route of the game.
