Yes, the Iraq war is awful, but so is the fact that this man ended the one life that G-d granted him. He could have spent his natural life--say, 20 or 30 more years--working for peace and reconciling with his family. I do not ascribe to your idea of martyrdom or that this is a noble death. Suicide is always tragic, never the right thing to do. Above all, we should love this world and this life and the people in our life more than any message. Maybe his self-immolation will help spread the anti-war message, but even if it does, think of the hurt he has caused to the people who knew him. Is it worth it? The real tragedy is that nobody could intervene before he took his life. Spread his message out of respect for him, and because it needs to be said, but don't glorify his death.
