Actually, it'd be more terrifying to have a collection of intelligent robots -without- emotions, because then it would lack compassion, empathy, and all that good stuff that typically prevents us from being mindless killing machines (of course, it doesn't really work for us either). Otherwise, what we're talking about is using the baser animal part of the brain which tends to include the survival instinct. Theoretically, anyway. If the sapient robots perceive humanity as a threat to their species, they may respond aggressively and mindlessly.
Using a brain, especially a human brain, with the goal to have the being think, adapt, and grow requires emotions. Hence, its exceedingly difficult to truly separate our "thinking" brain with our "emotional" brain.

In anycase, anything they can do now likely wouldn't harm us and of course they're not going to give weapons to something so new and unpredictable. However, once the technology evolves it will likely go, as everything does, to the military. And therein lies the real problem - could such a being be able to tell the difference between the sides of a war? Or could it understand why 'these' humans are bad but 'we' are not? (hell, I barely understand it)

However, I haven't read about bio-technology in a long while so I'm being entirely speculative.

I guess it could "adapt" to humans in a bad way, but in what cases would we want or need them to be involved with the military.
