Either way these people are killing for their cause and their way of life, whether it be a suicide bomber, or an ex-NFL player-turned Marine. Though the way they go about honouring their cause is different. A suicide bomber gives his life (which is courageous and noble) but he kills innocent civilians purposely. I'm sure all of us would be the same if we were poor Palestinains being assaulted and killed by Isrealies. Still marines DO end up killing civilians, but it isn't their intent.
Anyways, I still understand what you're saying.
