Are you avoiding the question? By all means, grace us with your apologetics of the god that made that man blind from birth. Because either "god did it" (for a number of possible reasons claimed by theistic apologetics) and then god is a moral monster; or then god didn't do it but is powerless or indifferent to stop it and then, why is he a god that merits worshipping?
Regarding the man blind from his birth, God sustains and permits everything that happens, even the (moral and natural evil).
God will sustain and permits the existence of evil forever (in an isolated way: Hell).
The cause of blindness of that man (his name was Celidonius) was not inherited moral evil but natural evil.
God is the only one who can make (greater) good from evil. That's the very point why Jesus said that.
Nobody else can make good from evil. If you start with evil you will continue with evil.
