Why the constant mention of "god" "God" "gods" "deity" or the like? One does not have to rely on the existence or non-existence of a "superbeing" to discuss whether we, as sentient life, armed with what seems to be an excess of "free will" at times, are capable of being responsible in these decisions.

From a theological POV, I suppose that if humanity were reduced to a collection of patentable proteins, then perhaps we will have lost the belief of the "sanctity" and "miracle" of life. Life will have become a commodity, like gold, oil, and weapons grade fissionable material.

As for the argument about "filtering" out disease. I suppose future generations, free from those problems could do without a Helen Keller, a Stephen Hawking, . . .
