Midas makes a bad decision to have everything he touches turn to gold. His greed rules his decisions and he overlooks the possible downsides to having this ability.
The lines that best support the theme that greed can prompt bad decisions are lines 3-4: <em>"Midas cried, 'Give my fingers a golden touch! / Then, I shall have a gilded kingdom and such."</em>
Explanation:
By reading these lines, the reader can see how greedy the character of Midas is. He can ask for anything, but what he wants is his fingers to have a golden touch, his desire is shallow, he just wants to turn everything he wants into gold and doesn't think about the other side of his desire. His choice is not the best and he can't see that because of how greedy he is.
