This will be a topic with much in the way of divergence of thought. One such challenge with genetic modification is the idea that the power to "play God" and assume a higher authority role is a distinct possibility. If one can engineer genetic code for one reason, then the blurring of the lines to continue this process can ensue. This can lead to genetic and eugenics experiments gone awry. At the same time, genetic engineering can lead to a great many improvements in the lives of human beings and can also result in cures for ailments and conditions that cause challenge to many. The costs and benefits are each very compelling, causing a great deal of debate, discussion, and a sense of "unresolvedness."
