If your speech craft is above room temperature, you can easily get eveyone in Vvardenfell to treat you like a rock star. At least the ones you don't need to whack.
True, Morrowind NPCs can be cold to you at first, especially if you have a low personality, but in time, you'll be able to get a much warmer welcome, of course, sometimes it's so warm as to become creepy, like the ever popular "I have a feeling that you and I are about to become
very close." line. Now, there's not anything you can do to stop people who want you dead from insulting you, but hey, you get to kill them, so it's not so bad.
