Playing G-D?
Yes
but then again i dont know what OP was referring to when he said gene editing
Yes I was referring to medical type of stuff. Although I guess that can be a concern of "designer babies".
Who doesn't like the idea?
I always see random people comparing it to eugenics (which that itself I don't understand what the big deal is) in a negative way.
is this hypothetical gene editing available for free to everybody?
IDK. Does it matter?
Is a doctor saving ones life playing G-d?
He already differentiated between an existing condition and a non existent condition.
