Do you think AI is inherently evil?
It's hard to say. It is scary to think that AI could develop cognitive and emotional intelligence, thus making it more human. Some humans are evil, so AI could be too. 
AI lacks imagination, so where could it acquire it's evil techniques?
It could acquire them from mimicking human behaviors. 
Could it be trained to do what Jesus would do?
I supppose. AI makes it possible to learn human-like tasks. 
So, how would it decide between imitating the Jesus who drove the money-changers from the temple and the Jesus who gave himself as a sacrifice?
AI would still have to be taught. We would need good humans to teach AI the sacrifices Jesus made.
So, you're saying that AI is nothing more than a trained dog that can only respond as it's programmed to? And because of that programming it can never achieve self-awareness?
No. I believe AI will always develop self awareness. The only thing humans can do is attempt to monitor it. The idea of AI forming it's own consciousness is a slippery concept.
Wouldn't it be wise for humanity to stop AI now? Just pull the plug on the computers and go back to pencil and paper?
