WTF Is Going On With All This Beheading!?

Seriously:

Brazil: Man confesses to decapitating British girlfriend

Canada: Decapitation suspect appears in court and
Man who beheaded bus seat mate defiled body, police tape says
He fucking ATE him!?? This headline is pretty silly, though. I mean, isn't beheading someone pretty much a defiling act?

Greece:Greek man held after girlfriend beheaded
He also cut off her dog's head!

I mean really, what the fuck is going on? Since when did beheading become an "acceptable" way to kill someone. I mean, there's no truly acceptable way, but you know what I mean, right?
