Because gen is getting soft he's not being all big and tough like most guys are
In "Kubla Khan," Coleridge describes the creation and destruction of Kubla Khan's palace in the exotic location of Xanadu, which gives the poem a dreamlike quality. Through the historical character of Kubla Khan, Coleridge uses the wild image of the Mongols to suggest that Kubla Khan is insane, implying that all creative actions are the acts of mad men.
The last lines bring the poem to a climatic close. Flashing eyes evoke the image of passionate creativity. By talking about "holy dread," Coleridge suggests that creation is both sacred and demonic.
Hope that helps :)
