Actually, funnily enough that is a very good point.
When we watch wars and devastation around the world on our nightly news channel does that make us opportunistic voyeurs? Does our government "allow" us to revel in the misery of others by not banning the broadcast?
You could argue that we have the right to stand wherever we want and watch whatever we want, and what goes on in front of our eyes is not our doing and doesn't reflect on us as human beings, however when we choose to press the on button on our TV or computers and select that station/video then we are purposefully entering their world for our own voyeuristic purposes and therefore choosing to use their misery for our own entertainment.
Interesting.
