Cain was justified in his murder of Abel

From Wikipedia " And the human knew Eve his woman and she conceived and bore Cain, and she said, "I have got me a man with the Lord." And she bore as well his brother Abel, and Abel became a herder of sheep while Cain was a tiller of the soil. And it happened in the course of time that Cain brought from the fruit of the soil an offering to the Lord. And Abel too had brought from the choice firstlings of his flock, and the Lord regarded Abel and his offering but did not regard Cain and his offering. And Cain was very incensed, and his face fell. And the Lord said to Cain, "Why are you incensed, and why is your face fallen? For whether you offer well, or whether you do not, at the tent flap sin crouches and for you is its longing, but you will rule over it." And Cain said to Abel his brother, "Let us go out to the field," and when they were in the field Cain rose against Abel his brother and killed him. And the Lord said to Cain, "Where is Abel your brother? And he said, "I do not know: am I my brother's keeper?" And He said, "What have you done? Listen! your brother's blood cries out to me from the soil. And so, cursed shall you be by the soil that gaped with its mouth to take your brother's blood from your hand. If you till the soil, it will no longer give you strength. A restless wanderer shall you be on the earth." 13 And Cain said to the Lord, "My punishment is too great to bear. 14Now that You have driven me this day from the soil I must hide from Your presence, I shall be a restless wanderer on the earth and whoever finds me will kill me." And the Lord said to him, "Therefore whoever kills Cain shall suffer sevenfold vengeance." And the Lord set a mark upon Cain so that whoever found him would not slay him." And Cain went out from the Lord's presence and dwelled in the land of Nod east of Eden. And Cain knew his wife and she conceived and bore Enoch. Then he became the builder of a city and he called the name of the city like his son's name, Enoch." I removed the numbers cuz they were annoying me lol but the story is completely unchanged. 1st round is opening arguments for us, later rounds are whatever, this is my first time debating lol My opening will now commence! First Point, God had shown Cain that blood was more valuable than crops. God had never explained to Cain the reason for his disregarding this particular offering. From Cains view it must have seemed that God favored the profession of herder over that of farmer, of meat over vegetables and grain. The story makes a point of saying that Abel chose the best of his resources while Cain by comparison must have only chosen the middling of his. Yet when we look at Gods own word we see "For whether you offer well,or whether you do not," Showing that the wellness of the offering had little to no effect on the outcome, at least to Cains ears. Second point. Murder could not be thought of as sin in that time. God said to Cain "at the tent flap sin crouches and for you is its longing, but you will rule over it." Remember that Cain had just seen his offering of crops ignored and his brothers sacrifice of a living creature celebrated. If, to Cains mind, farming was a sin but slaughter was not what precedent was there for murder beings thought of as a sin? There was none. So, again to Cains mind, if the spilling of blood was simply a part of religious life what sin could God have meant Cain to rule over? The sin of not spilling blood. Third point. The better the sacrifice the more blessing is received. If crops were low quality sacrifices and animals were good sacrifices it stands to reason that the sacrifice of a human would be the best possible sacrifice because human beings are the highest possible physical life form. After the murder of Abel Cain was both blessed and cursed with a mark that made tilling soil impossible but also provided him a safeguard against murder from other people. He was free to travel the world instead of being locked down to a single farm. Thanks lol.
