Because Lennie never has the intention to kill anything, he can feel an immense amount of guilt and remorse as seen when he runs out of the barn crying, “‘I done a real bad thing…
I shouldn’t of did that’” (Steinbeck 92), after killing Curley’s wife.
George clearly can sense Curley’s anger and vindictive nature about Lennie killing his wife.
It is quite apparent that Curley wants justice and revenge and is determined to make Lennie suffer: “Curley’s face reddened. I’m gonna shoot the guts outta that big bastard myself” (Steinbeck 98). ’ And he tries to reassure himself, ‘Maybe they’ll lock ‘im up and be nice to ‘im” (Steinbeck 94).
George killed Lennie because of his getting in too much trouble and people wanting to hurt him.
George only cared about Lennie’s safety and that no one, including himself, would ever mess with him again.
In the novella, Of Mice and Men, by John Steinbeck, George killing Lennie is a merciful kill to save others from Lennie’s unintentional acts of aggression, to spare Lennie from suffering a cruel death, and instead ensuring a peaceful and quick departure one that will cause George the least regrets.
George begins to see a pattern of aggression coming from Lennie and wants to put it to an end because Lennie is hurting too many others unintentionally and he sees Lennie is quick to frustrate and panic and is lacking in the ability to control his violent reactions.
Nonetheless, George sees that Lennie is unable to learn from his mistakes and fears the pattern is going to continue and that he is unable to change Lennie.
George feels justified in killing Lennie because he knows that in the long run he would be able to spare many other lives and prevent Lennie from all the pain and anguish from the remorse Lennie feels after his aggressions.
