When Lennie runs away, he takes the dead puppy with him, saying, "I’ll throw him away...It’s bad enough like it is." What does this show us about his mental state?

It's Child-like

Explanation:

The story "Of mice and men" written by John Steinbeck in 1937. It chronicles the life of two ranch workers George Milton and Lennie Small who looked for jobs during the Great Depression in California, USA. In the novella we learn that Lennie bounces a puppy on until it subsequently passes away. He really did not understand that the bouncing could have cause such harm to the animal considering what he was doing was not a "bad" thing and there was no mal-intent. He struggled with the realization that such an act can harm the puppy but not harm others. His mental capacity is still child-like as he is unable to make such a distinction.
