Changing Judge's mind about modifying humans has to be done through an ideological effort, not because of an end result that has to do with strength.
I don't know if you took the time to take a step back and look at what you are saying, but you are basically arguing that Judge needs to be proven that modifying humans is not the most efficient way to make them strong.
How the fuck does that prove him that the idea of modifying humans in itself is wrong
You are just making it about efficiency.
You are saying :
"Judge would have been right to modify his kids if they were stronger becasue of their modifications, so we must prove him that they are weaker and that's what makes it wrong"
You are doing jack shit to touch on the morality of Judge's actions and prove him wrong on that front
