God invented cloning, according to retired pediatrics professor Michael Thaler. That's how the whole thing started. So, you can't very well argue that the process itself is unnatural. Rabbis have agreed with this premise. A short, stocky man with gray hair, Thaler is a visiting scholar at Stanford's Center for Bioethics and professor emeritus of pediatrics at UCSF Medical Center.
Cloning offers potential medical benefits, for example, such as organ renewal.
You can replace bad cells with good ones. By engineering cells, he added, cloning could eventually lead to cures for diseases such as cancer. It must be beneficial and present the greatest good for the greatest number. As long as we are moving the world forward in a righteous manner we are acting in a halachically approved manner. Right now, the U.S. government isn't funding research into cloning.
