No. George knew Curley was going to kill Lennie and make him suffer. This is the reason he kills Lennie peacefully.

If this relates to Of Mice and Men, Lennie crushed it in the fight when he and George first arrived
George. After Lennie accidentally killed Curleys wife and went to hide in the brush (a place where George and Lennie agreed to meet in case of trouble) Curley and the guys set out to kill Lennie for what he did. George, not wanting Lennie to die like that, told Lennie the story of the house they planned on having. while telling Lennie he shot him in the back of the head.
Curley wanted to fight George I think, so he picked on Lennie. He hit Lennie a couple times and then Lennie stopped a punch in mid-air and squeezed Curley fist and brokenit ending his boxing career. Then Lennie Lille Curleys wife and he runs away and George kills him. :)
George worries that Curley is confrontational and aggressive, and may pose a threat to Lennie due to his small stature and tendency to pick fights. George is concerned that Lennie's lack of understanding of the situation could lead to trouble with Curley.
George reassures Lennie that he is not mad and explains that he gets frustrated at times but it doesn't mean he is mad at Lennie. George emphasizes their friendship and looks out for Lennie, wanting the best for him.
Curley's wife died, so now Lennie will be in trouble and then their dream of the farm will be no more. Candy therefor won't be able to work on the farm with George and Lennie.
The boss was suspicious because he thought George was trying to cover up for Lennie's lack of intelligence or understanding. He may have also questioned George's control over Lennie and their relationship dynamic.
After accidentally killing Curley's wife in "Of Mice and Men," Lennie flees to a nearby hiding spot in the brush by the Salinas River where George had instructed him to go if he ever got into trouble.
George plans to make it seem like Curley's wife's death was an accident by staging it as if she was killed trying to reach for Lennie's hair when he was defending himself. By framing it in a way that Lennie was protecting himself, George hopes to avoid any blame or suspicion falling on Lennie or himself.
george made Lennie feel strong he needed george to live and Lennie took evey word george said and though he forgot he would always turn to george and ask for him to help as there is a bit in the book that says george told Lennie to jump of a bridge into water and Lennie did even thought he could not swim and then thanked george for saving him.
Lennie is initially captivated by Curley's wife and sees her as somebody he can talk to and confide in. However, he eventually becomes afraid of her when she starts to show her flirtatious side, as he is worried about getting into trouble by angering George.
