Of course it isn't. Nobody is arguing that. People do stupid, horrible, and hateful things. However, that will be the case with or without robots.

So, for example, there's this thing that gets used by African warlords a lot called a "technical." There are different versions of it, but the most popular configuration is a Toyota pickup truck with a large machine gun mounted in the bed. You've probably seen it if you follow world news. They are very effective tools for warlords to oppress local populations because they can carry a lot of dudes, lay down fire, and they're really mobile. It's kind of the perfect tool for the job.

Now, Toyota didn't sell the truck with this purpose in mind and almost certainly doesn't condone it. Think about it though. Is Toyota responsible for this? Should they stop selling their pick ups because of it? I say no, but your milageay vary. Especially if you drive a 2005 Toyota Tacoma; 21 city / 27 highway.
