What pisses me off is that he probably WILL get away with it. He'll get the minimum of 10 years, maybe 15, and retain his precious "honor." While 4 girls remain dead.
He needs to not only die, but die dishonorably. Perhaps drowned in a vat of pig's blood. The death penalty alone is never an effective deterrant - especially in a culture that values human life so little. Leaving these scum even more "dishonored" on their way out may make some of them think twice - provided they are even capable of thought.
Go figure.
