A Monster's Viewpoint

I just finished reading John Gardner’s “Grendel”, a story from the point of view of the monster in Beowulf. I like this passage:

“Blood lust and rage are my character. Why does the lion not wisely settle down and be a horse? In any case, I too am learning, ordeal by ordeal, my indignity. It’s all I have, my only weapon for smashing through these stiff coffin-walls of the world. So I dance in the moonlight, make foul jokes, or labor to shake the foundations of night with my heaped-up howls of rage. Something is bound to come of all this. I cannot believe such monstrous energy of grief can lead to nothing!”
