Well, it's a bit more than that. People kill each other with whatever they have close at hand when they get into a fight; handguns are easily carried into a bar or on the street, which is why more people are killed with handguns than long rifles in America despite more of the latter existing. People aren't going to start carrying drones with propellers around in their pockets.
It could be used by some people who want to do targeted killings, e.g. in gang violence, where it could be better than other methods maybe. But on the other hand, RC helicopters able to carry and shoot a gun have existed since at least 2006: https://www.youtube.com/watch?v=bZCH1492CzA
The number of people who actually want to kill lots of people without being physically present is extremely small; so small that in a country the size of the US, one only crops up every couple decades, e.g. Timothy McVeigh.
I would make a solid bet that proliferation of cheap drones does not impact the homicide or terrorism rate in the US in either direction.
