Cowardice is exactly correct. Cowards attack unarmed people. They are mindless because these craven fiends use drugs to overcome their fears. Bravado is not bravery, and enslavement is not principled willfulness. Terrorists are cowards by definition.
For them attacking unarmed people is not cowardice because they know they will die. It is effect enhancement. Their goal is to make as many infidel dead bodies as possible. Cowardice is just a derogatory and for yall all derogatory words have the same meaning ie. BAD.Use the most evocative one. That is why all non libs are necessarily RACIST. That is the baddest word liberals can think of.
