I live in the Philippines and last December 25, 2016, there are Sixteen Hurt in Christmas Eve Blast at Catholic Church in Philippines. Sixteen people were wounded in a grenade explosion outside a Catholic church and its in Mindanao. I'm sure that someday, This terrorist will be punished accordingly by the rule of mankind and God.
It is impossible to hope in God. Punishment of the terrorists must be right and should punish people. I'm not going to convince you that there is no God, but if evil is not punished it will occur again and terrorists will involve new supporters.
