What part of "98% failure rate and horrible mutations among the survivors" doesn't he understand?
Good to hear that the world is continuing to go about its business "normally".
But scientifically, it is stupid. You see, there are two DNA types in a cell, the nuclear DNA and the Mitochondrial DNA (which is mainly famous for matching you with female relatives for you out there who are detective story junkies)
In clones, the nuclear DNA doesn't match the mitochondrial DNA. As a result, few clones live to maturity (it took 200 tries to get Dolly), many that are born either die quickly or prematurely age.
In other words, aside from all the embryos he kills trying to make one clone (for egotistical reasons), he also puts the surviving baby at risk
