Yes, OBL will become a martyr in the eyes of his followers. He won't be taken alive, so the chances of apprehending him to face trial in a court are almost zero.
If his death creates another 100 zealots, so be it. I find it amazing that there are those that still think appeasement is the best way to end world terrorism. If these people are determined to fight western democracies the only option for those countries is defence. Neutralize the enemy.
Edited to remove a comment about Hitler, it seems RVR 800 above beat me to it.
