Final answer:
If George hadn't shot Lennie in Of Mice and Men, Lennie would have faced consequences from other characters and potentially continued to unintentionally harm others.
Step-by-step explanation:
If George hadn't shot Lennie in the book Of Mice and Men, it is likely that Lennie would have faced consequences from other characters in the story. Lennie accidentally caused harm to animals and people due to his mental disabilities, and this caused tension among the workers on the ranch. George knew that if Lennie was to be caught, he would either be killed or put in a mental institution, neither of which would provide him with a safe and happy life. Additionally, Lennie wasn't capable of fully understanding the consequences of his actions, which made it difficult for him to control his actions and stay out of trouble. Without George's intervention, Lennie might have continued to unintentionally harm others, leading to further conflicts and potential danger for Lennie himself.
