How is the corruption of power explored in 'The Trial' by Franz Kafka?

Corrupt state bureaucracy is an impenetrable and omniscient power that controls everything; defiance is futile. In rare statements contemplating societal institutions directly, Kafka found that those same ‘organised and socialized concerns with which he thought it necessary to associate himself were, in themselves, corrupt’, ‘Kafka was repulsed by the sham, by the dishonesty, by the cheating use of strength and intellect to overwhelm the innocent, helpless humanity.’ As evident in The Trial, the immense and permeating power of the courts oppresses all. ‘It was a portrait of a man in a judge’s gown, who sat enthroned on a raised gilded chair; the gold shone out of the canvas’, the brandished wealth and power is apparent by the ‘gold’ ‘gilded’ chair and way that it is ‘raised’ proves how he is above humanity, physically and symbolically. In addition, the power of the courts is not simply contained within the painting, instead Kafka transcends their surface regality to metamorphosize physically by ‘the gold shone out of the canvas’, thus the gold, and therefore their power is palpable.
