The whole entertainment business and media is also part of the problem. When the entertainment world keeps showing movies like "Saw" and other massacre movies, it has helped desensitize human being. On top of that, the constant coverage of war and isis and all sorts of anti human sentiments are being shared in the mainstream by media, further desensitizing what is left of humanity.

These things may not sway well educated people but these things have a very major impact on the uneducated and the pseudo educated crowd. Thus we are seeing more and more heinous crimes against humanity, and even more so against women who are physically a bit weaker on average than the average male.
