Really it's all about people individual perceptions.. You can say neither is evil or good but what is evil or good? I think we decide each of use for ourselves what is evil.. So really this debate is just people giving their own opinions, so in my opinion it is just best to read about the factions and see what feeling they give you.. I didn't think the Dominion were evil i just though they were control freaks, who committed evil acts, that i grew to dislike the more i read on them, but that's my opinion. And the Exiles just seem like a rebellious gritty group which i just identify with more and more.. But who's saying they can't commit evil acts? The Mordesh aren't exactly cute and cuddly you know? And being cut off from their Dominion where are they going to get their suppliers? They probably turn to piracy and raid innocent Dominion civilians..? So yeh i think they're both capable as evil as we all are but neither is by definition "Good" or "Evil" in my opinion.
