Exactly.
I noticed that many female players tend to romance female NPCs, which made me curious as to why. I remember Miss Kitty at the Interplay boards complaining about the lack of heterosexual female romances, then it occured to me that there's no demand! Perhaps I was wrong. But then, who could resist romancing Viconia?
Lol! I sure can. Sorry to dissappoint - but I could never ever even pretend to play a female-female romance. Not that I object, mind it. I find it fascinating to read about and very very romantic. But to make a PC for this kind of a romance... It is just ... how should I put it - not enticing for me as it will completely lack an ooomph factor even in my imagination. Even with Vic.

I adore her, but I would rather be friends with her - a heck less of complications.

So - yeah, there is not enough male romances, and the ones that exist do not satisfy me as player. Either too 'sweet' or too 'unimaginative' or not 'enticing' (as in lack humor and zest), or just plain boring.
So, does he even have the slightest chance of redeeming himself, or is there something attractive about calculated, evil men? Maybe becoming good or neutral would change him into someone who no longer possesses whatever made him so charming in the first place. His personality would be lost in the transition (so to speak).
Mind it - I am involved with this romance , of course, and as such I cannot be objective. But from what I saw written and how the plot is build - Edwin remains Edwin, as in: self-centered, boastful, vain, extremely clever, humorous, talkative and - from many female POV - completely adorable.
As for 'calculated evil', hmm, I never found Edwin calculated evil - rather a very very shy of showing any 'sensitive spots', and very good at pretending to be 'evil'. So good, he can actually fool many. But then - I don't believe people can be actually separated by 'alignment' system , even using as 'many' as whole 7 different combination!

For consolation of 'black and white' minded individuals - there will be a possibility for Edwin to switch alignment, but I personally think it is not that important. More important is the fact that he gets to keep his personality.
PS
I am only going into this long-winded rant mode because I saw your other posts and I dont consider you a 'troll' - I think you are honestly curious and just wanted a good discussion - right? Please prove that it is so, by accepting that diversity of mods and opinions in this forum is something to be proud about, not to regret.
Best wishes,
