Sickos around us!

I just need to get this out, otherwise I will EXPLODE!  What is going on, what goes through some sick bastard's heads, it is insane.  I read today about a single mother and her two babies being raped, the mother and the one year old have tragically dies, while the 2 year old is fighting for her life in hospital.  What sort of pleasure can some twisted, sick person get from performing such horrendous acts.  I could actually throw up this is just that sickening to me.  I just cannot comprehend, its just SOOO beyond me...
