This is something that has been said since a long time, but I am convinced that the increase of violence in our society is greatly amplified by cinema, TV and video games. Call me a killjoy, but look, in most movies you see people killing others, being killed, shooting at anything that moves, detonating everything, not to mention all the collateral victims of these action scenes. All this makes violence something trivial and common. Moreover, with the search for a PG-13 rating by movie studios, we are left with movies for teens packed with violence and murderings, but as we do not see blood or bullet impacts, well, that's all normal. Just as in video games! Kill, or being killed, well, who really minds, as you will resurrect immediately and continue! So it is not surprising that some passes on to the act in real life. Thanks to all this continuous violence flowing out from our screen, killing another being has become trivial and easy.
