Should I pick up Dorn?

I'm running an evil/neutral party.

  1. MC - F/M/T male Neutral Good, romancing Vicky

  2. Korgan

  3. Jaheira

  4. Viconia

  5. Edwin

  6. NPC rotation

My goal by my CHARNAME being Neutral Good is to romance Viconia and keep my playthrough from being truly straight-up evil, choice wise, but so I can also enjoy my F/M/T alongside Edwin's magical superiority, and also the evil characters are new to me since I've always done good parties.

Question is this: will taking on Dorn force me towards straight-up evil choices? Will his character-arc/quests complicate things? Is he a bit too "evil"? Vicky, Edwin and Korgan all seem to be simply selfish and "evil lite", which I can handle.
