While I am not against research into genetics (I'm sure if I ever lost a leg I would be grateful for the ability to grow a new one) I agree with your analysis that we are on dangerous ground and could one day find ourselves in a society where 'inperfect' people are looked down on and maybe not even given the opportunity to be born in the first place. And by 'inperfect' I am talking about minor stuff bent noses and brown eyes. But that is an issue of human vanity and should not halt scientific progress that could help mankind if used sensibly. It is often said that Science is responsible for the means but not the ends, and I agree.
