The "LIGHT" is all encompassing and cannot be completely comprehended by us; IT/HE is not responsible for the attacks on 09/11. Those in the Twin Towers (in my opinion) are not responsible but it is rather those "evil-doers" that orchestrated and planned the attacks who are SOLELY responsible.
Man's inhumanity to man is the root of all evil and the opposite of "love your neighbor as yourself," as preached in both the New and Old Testaments. (BTW, this same short-circuit in the universe was responsible for the destruction of both the first and second Temples in Jerusalem.)
These crazies who caused this need to be identified, sequestered and permanently removed from society (however that can be accomplished) so they're never able to do it again.
