* Lennie Small: Lennie is killed by George, who shoots him in the back of the head to prevent a more painful and violent death at the hands of Curley.
* Candy's dog: Candy's old dog is shot by Carlson, who argues that the dog is suffering and should be put out of its misery.
There is also a strong implication that Curley's wife might have been pregnant and therefore, the baby could be considered dead as well.
It's important to note that the deaths in the novel are not merely plot devices; they carry significant thematic weight, exploring issues of power, cruelty, dreams, and the fragility of life.
