So why -should- you be evil? Because you know what's best and will subjugate or kill anyone who thinks otherwise. So get on it!
Okay, but by that logic, I should just kill everyone, because none of them can be subjugated.
My point is that if Larian wants us to play evil, our character's need a valuable reason to choose that path. Homicidal Maniac and Goblin Fetishist aren't the best draw for most people.
You are not drow, you are half drow therefore you are useful only as fodder, plaything, latrine boy, or food for my other pets! Also as of the moment you are low level, and an unknown, and if your male then therefore you are weak do to you not being half drow, and also male. Also you are not of the same house (if drow in goblin village has one) so therefore you are fodder, or a potential rival. Rival since you are half drow and/or male is highly unlikely an opinion to a female drow. So what is happening is you've already been judged by the drow, on several drow merits found lacking, and so you rate equal to goblins, humans, etc as fodder, slave, etc. Your options then are to prove yourself useful and therefore deserving of a very slight amount of attention like a much unloved dog will on occasion in a pat on the head. Or if it's an option (unsure if it is) kill her and replace her in some way shape or form.(again don't think it is an option. cause goblin army can upset the balance.) Yet by following her you are following the evil path and may be awarded further down the road for it. maybe you'll get trinkets, some time alone with her if found pleasing etc.
Being evil doesn't mean you serve no master, you have one just by being a Warlock. It means your allies are also your enemy. The opposite is not true, and it is harder to please evil then it is to please good. Add to this that it's a drow your dealing with, who have a very narrow view of other races, since they are the usual steroetypical bad guys (superior race) and if your male it lowers you even further do to Female Drow having a higher social status then males.
