genetic engineering to elimate mutations

based on my research i believe that the genetic engineering of humans is wrong because i feel if we were to go through with the genetic engineering of humans we would lose a lot in the world to day plus we could be looking at more abortions because women would want the perfect child. we would also be look at segregation again between natural selection and those that were genetically engineered. i feel that if we were to do this that it should only be used for cancer and other major diseases like it. we shouldn't be using it just to make a perfect kid or the perfect athlete or anything like that. i f feel that my peers would thing the same because of all the risks that stand by on this subject. i do feel that genetic engineering of animals is okay because that's how dogs and cats and other animals were brought into the world today.
