I mostly support genetic engineering, but I'm just afraid of the possible side affects.
It's possible that a genetically enhanced person could become too... arrogant and powerful. It could start a huge war if the guy had too much power and things got out of hand.
Or just in general, genetically enhanced people using their status against others.
Also, too many people might start having "customized" babies. If someone wants a boy, they could have a boy. If someone wanted a baby with brown hair, then they could have the fetus'/embryo's/baby's genes modified for hair color.
Why do I still support genetic engineering?
A good thing would be all the diseases that could be cured. Maybe our lifespans could go up too. Also, who knows what other discoveries could accidentally happen as a result of genetic engineering research?
