Help me reword these sentences from my essay?

If you think they are okay as it is, please say so, or give some feedback. If you can shorten it, if the sentence works without a word, please tell me.

Thesis:

-this one seems like a run on, could anyone rephrase this?

"Curley’s lust for revenge leads to his indifference toward Lennie’s humanity."
