Many have argued that George did the wrong thing of killing Lennie and that this makes him a bad friend. George isn’t a great friend either. He’s grumpy and bossy. The way George behaves towards Lennie is just very horrible.” if I was alone I could live so easy. ..No messes at all…stay in a cat house all night… I could put you in a cage…” George may have exploded and spilt all that anger out by mistake but when someone says things like that part of it must be true. George has his moment of frustration and that understandable but Lennie is like a child and they too make mistakes so Lennie can’t be blamed for being born with a mental disorder. He also makes lennie seem like a burden. “Whatever we ain’t got, that’s what you want. God a’ mighty, if I was alone I could live so easy. I could go geta job an’ work, an’ no trouble. No mess at all…” Lennie can bring trouble to a person’s way of living. He has to be looked after and it makes George question and blurt out that taking responsibility of Lennie is too much to handle. These quotes signify that George had in fact been a bad of a friend he was to Lennie.
George did the right thing by killing Lennie and he did it for the right reasons not negative ones. Candy tells George that he should have killed his dog but he was being selfish and didn’t end his dog’s misery himself. "I ought to of shot that dog myself, George. I shouldn't ought to of let no stranger shoot my dog."
