Iraqi Suicide bomber blows up own family

(Ramadi)  In an incident which I have to admit surprises even me, a suicide bomber in Iraq walked into a family house while they all were sat down for a meal and blew himself up. The difference here is the house belonged to his cousin and the wife of the suicide bomber along with 3 of their children were sat down at the table. (Actually the floor)

What kind of sick f-ck allows his family to die in this manner?
