How does Les describe or define corruption?
Corruption is likened to an old rotten potato—something vile, repulsive, and smelling to high heaven, which no one wants to touch. In the context of the earth, it denotes a morally decayed condition accompanied by violence, with corruption and violence going hand in hand.
Les explains that when he sees the word corrupt, he first thinks of an old rotten potato, which smells and looks worse than anything and is something vile that you don't even want to touch and that smells to high heaven. He applies that description to verse 11, where the earth was corrupt and filled with violence, noting that corruption and violence went hand in hand. He also describes the human race as always trying to beat the system, which prompts more laws and corrections, and says that back then all they could think about was how to be wicked in some other way.
