Do robotic planes and other things that kill at a distance make it too easy to kill?

Nowadays, a person can sit in the backyard of their suburban home, and control an unmanned predator aircraft halfway around the world. You can watch the video screen, and, when you want, punch a button and blow someone up. Apparently the CIA and other US forces are doing this with increasing regularity. Back in 2001, the PotUS had to approve every kill. These days, people at much lower levels are approving the kills.

We live in a videogame world. We play all these games involving killing bad guys. We train pilots and all kinds of other military personnel in video games. The science fiction world that Ender lived in is rapidly approaching us.

Is it easier to make a decision to kill when the person is just an image on a video screen? Should the US government be making it so easy to choose to kill someone? Do we devalue humans when we aren’t in their presence? When their lives are more theoretical?

If you had to kill someone, would you rather do it remotely or up close and in person? If you choose remote killing, do you think the remoteness changes your value for life?
