I think overall more diversity to why you choose a certain route (whether it be evil or good) would make the options make sense for a larger group of players. Not every evil character is going to slaughter the tieflings because it may not make sense for their cause/purpose, despite that fact that they're evil. And I agree with the reward comments as you currently get rewarded much more by siding with the druids. I'm interested to see what Larian will be doing to make the evil route(s) more immersive and appealing in the full game
