Computers don't think; they use math at the basis of their logic, unless they have bugs the outcome always should be the same; meanwhile human brain uses chemistry and biological tissue to process.

I agree with what OP says, but I can't help that majority of consciousness is based in fear. Put it other way: I don't believe consciousness can exist without fear [of being destructed] ever present. And that's the challenge of programming machine with built-in fear: if I fall, then I may die. I'm scared of dying, so how can I do my best not to fall?

Computers are quite capable of executing stochastic algorithms. And neurons can be considered as analog logic units too.

Yes, and... ?

What about if you disable the machines video cameras for a while, as a punishment? Do you think it could learn to fear that?

You and I can understand death without actually having experienced it. Surely a machine could too.
