I think that would be a more dangerous road than the pure logic scenario. It is hard to detect people with emotional/mental instabilities. I would hate to think of an AI having thoughts like Jeffrey Dahmer or any of the other serial killers. What if an AI had the emotional appeal toward people that Hitler had? Cold and impersonal AI would be an easier thing to deal with a thinking feeling AI.
Of course that is just my opinion. I see the bad side of AI more than the good side. AI could also be an altruistic AI, and care about the welfare of people. But like I said I see the bad side much more than the good.
