Path, put it best in another post.
More to the point, the koran is clear on the treatment of infidels - kill them all, kill what you can, and Mohammed and Allah will be pleased and you will be blessed. There is no amount of sugar-coating by CAIR or its minions in gummint that can change that. So this is not an individual case of a sociopath, although that claim could be made against all of islam. When you are raised that way, taught to do kill those not like you (and that applies to Sunni if you're Shi'a and vice versa), you cannot claim a psychological disorder - it is an inherrent part of you.
Brilliant!!
