This is a good one. Genetic engineering to make a person superhuman or have some special traits, in my opinion, is wrong. If we weren't created a certain way, we shouldn't be changing this. Who knows what could go wrong?
Genetic engineering can be used under certain circumstances, of course! If a fetus or whatever looks like it's gonna be born with some mental/physical problem, maybe genetic engineering is the right solution! Maybe children of the people who are dumb enough to smoke and drink while pregnant will still have good lives! I do see the problems though, why would the parent get the genetic engineering? I'm sure you can see what I'm driving at though.
