I don't really feel like writing a 10-page essay in response, so here's the short version: While I agree with some of those statements regarding the darkside, having played both, I just can't see myself playing lightside again because it is boring, and being "Goody Two Shoes" just isn't my style.
Besides,there was one good thing about playing the darkside; I got to betray & kill Carth, that alone makes it worth my while.
