“Like all the new technologies that have arisen from scientific knowledge, biotechnology is a tool that can be used either for good or for evil purposes. The role of ethics is to strengthen the good and avoid the evil.”

Context: The Lord created us in His image and likeness, and we are the image of the Lord, and He does good and all of us have this commandment at heart: do good and do not do evil. All of us. "But, Father, this is not Catholic! He cannot do good." Yes, he can. He must. Not can: must! Because he has this commandment within him. Instead, this "closing off" that imagines that those outside, everyone, cannot do good is a wall that leads to war and also to what some people throughout history have conceived of: killing in the name of God. That we can kill in the name of God. And that, simply, is blasphemy. To say that you can kill in the name of God is blasphemy.
