Advantages and Disadvantages
The movie GATTACA, they use a new type of DNA sequencing to form offspring's with no flaws. This has some advantages but on the other hand it has some disadvantages. If we had a society like the one in GATTACA, we would have very few defaults or mistakes in the society. Everyone would be perfect and flawless. But on the other hand, no one could express themselves with their mistakes. We wouldn't be able to learn from our mistakes. If we were to also allow genetic engineering, the normal people, "Faith Babies", would have the menial jobs and would be treated as second best and they would be known for failing or never succeeding at anything.
A World Without Misfits
If we were able to get rid of all of the trouble makers and the different people in our society we would probably fall apart. Every single one of us have an important role to play on earth, whether your smart, shy, funny, annoying, we're all important. If there weren't any people with problems we wouldn't have jobs that help figure out what is wrong with them. The crazy people need the sane people to help them, the not so smart people would need the smart people to help them. We all seek help from other people but if we are perfect and think we can do it all on our own we may never succeed. If we were all little angels there wouldn't be anything unique about a single one of us, but since we all have different personalities we all are very unique.
Should it be Allowed?
Genetic engineering should only be used for those family's who really are in need of it. If they have a family history of diseases, they could get their child's genes rearranged in order for their child to have a little chance of receiving that disease. This should be allowed to those who want their kids to live a normal life. Not worrying about falling down and always getting hurt or getting really sick and have to go through kemo. Parents want the best for their children and by giving them a care free life is a good start. I don't personally know what it is like to have a disease or a physical defect but I know I would not want my kids to go through that.
