-Christians, even regular, ordinary Joes who don't think to much about the existence of God - for the intensity of their love to far exceed their capacity for blind, uncritical hatred, when the two vie for possession of their soul. But then, they're 'nut jobs', so that is only to be expected.
On the other hand, it is almost a defining characteristic of the more brutish Republican, to be more than prepared to injure their own children - if not physically, as does happens, too - psychologically, and this, merely to spite, to get their own back on their wife or partner, who finally treats them with the contempt they always merited. In short, their hatred will completely overwhelm any love they might have managed to muster, so may God help any innocent and vulnerable soul they can use as a pawn in the service of their hatred. The control freak freaks out, or rather lets what he always was all hang out.
Zarqawi, of course was no innocent, but he could scarcely be blamed for returning like for like, to aggressors who insist on continuing to outdo him in their demonic savagery, i.e. the Neocon leadership; at least, blamed by a man such as Mr Berg, who
a) prefers to grieve, one of the most Godlike activities we are capable of as human beings, rather than rage and fret and hate over something that cannot be remedied in the here and now;
b) would be infinitely more likely than our crass 'friends', to have reflected on the whole context of his son's death, the war, the suffering so wantonly caused by his government to innocent Iraqis and their families; maybe the personal circumstances of the man himself.
However, something like the broader picture of Zarqawi and his works was described in the UK Daily Mail, under the heading, 'Ironically, it was the US who created Zarqawi'. To read the whole article, click on:
