there are in the poem some vivid touches of the right kind-as ba se wyrm onwoc , wroht was geniwad ; stonc after stane , 2285-in which this dragon is real worm , with a bestial life and thought of his own , but the conception , none the less , approaches draconitas rather than draco : a personification of malice , greed , destruction ( the evil side of heroic life ) , and of the undiscriminating cruelty of fortune that distinguishes not good or bad ( the evil aspect of all life ) .
