I recently heard a well-known researcher, Julian Savulescu, suggest that we should use drugs or genetic modification to make us better people. Researchers have found that drugs can make people cooperate better and less prejudiced among other things.
But can drugs make us better? Drugs interact with our brains and alter chemical reactions, but when God created man in His own image, He gave us something beyond our mere chemical makeup. He gave us a mind. If altering our chemical composition to make us "better" would truly work, God would have done that from the start. He didn't because He created us to have free will, not to be robots.
A drug to make people cooperate won't make a better world. We have a very short memory if we think cooperation is always a good thing. One psycopath plus a bunch of cooperative people equals Nazi Germany and the holocaust.
It really would be better if we tried morality God's way.
