The idea is, are you basically a good Drow or evil Drow?
Honnestly this is nearly my only problem related to this thread. Should our races and subraces choice influence our "alignement" and how the world react ? According to me : no. A drow is a drow and good actions should lead to good reactions.
I don't really care but I don't understand this choice about drow as a race with subraces. This is even not really subraces...
