Well, i just decided to try being evil for once. So i got virg, sogg, the dog, and jeffy (necro guy). i also carry around the black helm, and make all my followers wear it till they are -100 align, 100 ma. Works out quite well, sogg is a beast in full magic gear, since it functions at 100%. one thing ive noticed, is that neither sogg nor virgil has complained about me being evil. is this because i made them evil as well? or do they just dont care how vile and such you are normally? im kinda curious about this, as i have never played an evil char before.
Maybe you have high Beauty, Persuasion, or Charisma. AFAIK, reaction from NPCs comes from your reaction modifier.
