Mercy Killing pt. 5/6

In Of Mice and Men, George kills his best friend Lennie. George didn't want to harm Lennie, for he was his more then a friend, he was family. But George had to or else Lennie would have a slow miserable death. Lennie loved soft things, while he was feeling Curley's wife's hair he accidentally broke her neck. He didn't know his own strength. Curley was enraged because he loved his wife so he said "'I'm gonna get him... I'll kill that son-of-a-b- myself. I'll shoot 'im in the guts'"(96). George didn't want his only family to suffer so he decided to put him out of his misery. Lennie died dreaming of what he wanted most. What would you do if your best friend (practically family) was going to suffer? Would you put them out of their misery?
