BEIJING (Reuters) - China over the years has derided the Dalai Lama as a jackal in Buddhist robes, choreographer of a separatist Peking opera and, lately, instigator of a plot that led some Tibetans to set themselves on fire and other forms of protest. Even so, China's hardline rulers may have reason to miss him when he's gone. The aging spiritual leader's presence and message of non-violence have kept a damper on unrest but, once he dies, things could worsen rapidly. ...

Al Jazeera did not cite a source for the report that was carried in brief headline.
