OMAM Part 5

In part 5 Lennie accidentally kills Curley's wife and after finding out Curley gets riled up and wants to kill Lennie himself. I believe that he wants to kill Lennie so badly is because Lennie was the one who broke his hand and killed his wife. He knows Lennie did it because he was the only one strong enough, "That big son-of-a-b*tch done it". One can't blame Curley for wanting to kill Lennie after what happened. You can tell that Curley is desperate to have his revenge and wants justice.
