it can actually help. I agree with the first 2 points, but to some extent, I agree with point 3 too, that they can have moral and ethical implications and would steer society in a negative direction. But as with anything that has pros, it has cons too. so I would say that the morals and ethical implications and manners depend on the brought-up more. so those who are unable to conceive or are having some other genetic or any other issue, at least they will be Blessed with a healthy baby, they can teach them morals by focusing on their brought up.
