I'm having hard time believing that Sayid, Claire, and Sawyer would actually join the Dark Side of their own free will. Yes, I know that they've all lost the person they cared for most in the world. Yes, I know that they blame people on the other team (Sayid blames Ben, Claire blames Kate, Sawyer blames Jack) but would they seriously trade-in their immortal soul?

What has the "Good" Side ever done to convince anyone they're good?

They've constantly lied, murdered, lied, hid the truth, engaged in deceit, insisted they should be trusted, tortured, and imprisoned people, all while lying and refusing to tell the truth.

I'd throw in with ZombieLocke if the other option were those douches in the temple.
