Connecting Curley's Wife's Murder To Lennie's Murder

I found some connections to the murder of Curley's wife and Lennie. The first connection is how Lennie doesn't want to kill Curley's wife, but because he doesn't know his own strength, he does. So, in Lennie's case, the death of Curley's wife is accidental. George on the other hand, is intentional in his murdering of Lennie. But neither George nor Lennie want to hurt or kill anyone (except maybe Curley). I think that both of the killings are forced because Lennie doesn't know how to control himself, and I think George feels pressured to kill Lennie for two reasons. One reason might be because if he doesn't kill Lennie, then Curley may be more suspicious and think that George also played a part in killing Curley's wife. Here, George was worried they would blame him, so he asked Curley to, "...come out and tell the guys about her, and then I'll come along and make like I never seen her. Will you do that? So the guys won't think I was in on it?" (95). Another reason could be because Curley would kill Lennie for him if George didn't. Curley would, "...get 'im lynched. Curley'll get 'im killed" (94). Which he would do to seek his revenge on Lennie for ruining his hand and killing his wife. I think that then maybe George would want to kill Lennie himself instead of having someone whom he despises kill Lennie, kind of like how Candy now regrets not killing his own dog to put him out of his misery. George could have also thought that it be good for the both of them. Lennie could be in a happier place, and he would be free of constantly acting as a guardian.
