In the novel, The Round House by Louise Erdrich all Joe wants is to get back at Lark, the man who attacked his mother, and give him the justice Joe believes Lark deserves. Joe will go to any length he believes Lark deserves, meaning Joe is willing to kill. Joe never thought killing Lark was a bad idea, and never second guessed himself. When he was shooting the gun I believe Joe was just nervous about taking the life of someone else, but he never didn't want to follow through with the plan. He knew that his fear would pass once he had committed the crime, even though he was shaking and had to have Cappy finish off the job. Joe got justice because now that Lark is dead he can't harm anyone anymore and can't walk free like the justice system believes is alright in this case. If they can't lock up Lark for good than matters will have to be dealt with was Joe's thoughts.
Joe's actions show that no matter what he is willing to protect his family and help them in any way possible, even if it means killing someone. Joe believes he got justice because he had this idea of killing Lark in his head since the day he found out his mother was attacked. He isn't afraid to go as far as possible to get what he thinks is right out of a situation. I believe Joe's actions represent him as a consequentialist. "Now I knew fear, I also knew it was not permanent. As powerful as it was, its grip on me would loosen. It would pass," (Erdrich 264). No matter how afraid Joe is to kill Lark he knows it will pass and Lark will die, he isn't afraid of the consequences the might come upon him. According to the definition of consequentialism "if a goal is morally important enough, any method of achieving it is acceptable," (Wikipedia). Joe follows that out by doing the worst thing you can do to a person. Kill them.
