The Bible has passages devoted to denouncing those who drink blood, because drinking blood is taking another's life source. God gave people their lives, therefore, everyone is entittled to their lives as deemed by God we should do.

The problem isn't so much people's individual rights, as it is society's disregard for other people's innate right to be themselves. So many times people feel entittled to make laws, torture those who do not conform and wage wars on eachother. As for slavery, it is an abomination. That is the most outrageous intrusion to another person's life.

Who knows were the World would be today if so many philosophers were not killed before or after they first shared their ideas and thoughts with everyone. The course of ignoring personal rights has slowed society's growth and well-being.
