All types of people are needlessly murdered by all sorts of humans under all sorts of circumstances. There is nothng particularly special about this event except that some attempt to use the event, in and of itself, to conjure some sort of social, or religious or pesonal example and extend it to the larger human scene. Such acts have taken place throughout recorded history (as well as in unrecorded and fictional history).
Those who attempt to apply a terrible event such as this to the conditions/behaviors/views of specific humans/groups/laws/scriptures, etc. usually are attemting a long/thin stretch. No matter the motivation for such an attempt, it shows itself as weak.
Indeed, there do seem to exist some "natural" human conditions and laws worth reflection in such seemingly unnatural cases.
With regard to those who try to apply certain "religous", or "scriptual" or general denomination doctrines to such an horrible event and extrapolate a conclusive view from there, the quest often resembles rather gross gamesmanship.
In contrast to all of the wading through and slicing/dicing the many "laws and rules", with regard to Christanity it might be good to reflect on the fundament that the relationship between the person and God - and the concomitant expectations - is a very singlar and personal relationship.
