What word or expression describes the attitude of "if I can't have it, nobody can"? [closed]

"Dog in the manger" is the phrase used to describe this attitude. "Spiteful" might serve if you're bent on a single word.

"The story and metaphor of The Dog in the Manger derives from an old Greek fable which has been transmitted in several different versions. Interpreted variously over the centuries, the metaphor is now used to speak of one who spitefully prevents others from having something for which one has no use. Although the story was ascribed to Aesop's Fables in the 15th century, there is no ancient source that does so."
