Back on topic, yes Vhailor whacked the snot out of Trias in my game too. The advatages of the different outcomes are as follows:
+ You let Trias go, and Vhailor doesn't kill him (either he's too far away, or he's not in your party): You can buy the Tattoo of the Redeemer (and alignment becomes more lawful and good) but you miss Trias' weapon and scroll.
+ You let Trias go, but Vhailor slays him: you get the Celestial Fury Scroll and the Celestial Fire Weapon (no alignment change of you yell "Vhailor, no!" - you become more evil if you just watch the fun)
+ You say you'll let Trias go, but you kill him anyway after he tells you what you need to know: You get Celestial Fire and Celestial Fury, and you can buy the Tattoo of the Betrayer (alignment becomes more evil and chaotic)
+ You just kill Trias: You get the Celestial Fury and Fire. (alignment becomes more evil)
Personally I think the second is the best outcome: you lose no alignment, but you get the Weapon and Scroll.
