Engenetics is perfectly fine within society, there is absolutely no problem with it other then cultural beliefs but if it against yours then just stay away from it. Many genetic disease could be prevented and cured. With the various uses for this there is no reason for banning this incredibly useful tool. This has the ability to cure cancers, trisomal 13, and many other genetic issues.
Engenetics is very unrealistic. In the real world problems may be solved, but it would be unethical. Certain types of people would be eliminated. the people would not want certain types of kids, and this would eliminate this traits from this kids. The kids would be nearly super human, living for very long times, and eliminating the chance of natural predators, such as, cancers', heart attacks, tumors, etc. The world would begin to create chaos from the "Super Humans".
