You did well.

Hasan, imo, simply snapped. I think it was because his duty was to counsel and debrief soldiers returning from the area of his homeland, likely explaining how they killed his countrymen. I am sure they soldiers did so in the naturally selfish manner people adopt when having their heads shrunk. They simply do not consider the feelings of the counselor. What I think set off the powder keg was him learning about his pending deployment. I did see a report that said he uttered a short prayer before the shooting started, in typical terrorist fashion, but that is unsubstantiated, so I don't know.

So, no. I do not think his religion drove him to kill our heroes.

Responsibility does elude my characterization. It does not fit at all, and for a different reason than you imagine. It does not fit due to it not really being the true motivation of such issues, such as Environmentalism, or Employee Safety. For example, the Employee Safety issue is a liberal one precisely because they would rather the Company be responsible, as opposed to the individual. Proof: It is the company, not the unsafe employee, who gets fined by the government for unsafe practices. Blame the company, the law states.

As someone else argued in another thread, if you have to go back a few millennia to find proof that religion is terrible, it shows the weakness of your argument.

I agree that responsibility if the other edge of the Freedom sword. The difference is: I feel that it is "Personal Responsibility" (Conservative value), not someone else's responsibility (Liberal value).
