Blood and Destruction.
Genesis 4: 8-12 "And Cain talked with Abel his brother: and it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him. And the Lord said unto Cain, Where is Abel thy brother? And he said, I know not: Am I my brother's keeper? And he said, What hast thou done? the voice of thy brother's blood crieth unto me from the ground. And now art thou cursed from the earth, which hath opened her mouth to receive thy brother's blood from thy hand; When thou tillest the ground, it shall not henceforth yield unto thee her strength; a fugitive and a vagabond shalt thou be in the earth." When blood is shed it is a wicked thing. even if in revenge, retaliation, riot, abortion, murder, manslaughter, violent robbery etc. It is wicked and it has terrible consequences. Cain killed Abel out of jealousy and envy and when the reward came he knew he was doomed. Bloodshed is a wicked thing before God and whoever is involved
