That depends, really. I find that I get bored pretty swiftly when interacting with any character that tries to define itself as being 'wholly good' or 'wholly evil'. After playing the likes of Final Fantasy XII, Final Fantasy Tactics and Vagrant Story as well as being an avid fan of the ASOIAF novels that inspired Game of Thrones i'm more keen on shades of grey rather than outright 'good' or 'evil'.
Another major issue is that it's very difficult to get morally questionable role-play going without a huge band of 'heroes' rushing to try and save the day, usually with the flawed expectation that the 'good guys should always prevail'. What's worse is that this attitude tends to lead to many role-players refusing to acknowledge that things are not nearly as black and white as they believe. There was no shortage of role-players back in WoW who branded the entirety of the Horde as needing to die whilst conveniently ignoring the flaws and war crimes of the Alliance, for example.
