Is George right to kill Lennie?
In my opinion no one should have the impudence of taking the life of any human being, only God has the authority to take somebody’s life. Although Lennie would had suffered more if he got killed by someone else.
There were two things to do after George’s realization that Lennie had killed Curley’s wife: either help him like last time in Weed or take courage in his hands and kill him before he could do more damage and before anybody could do it for him. Personally I would had put him in a mental hospital, but Steinbeck chose what to do with him.
