Do we REALLY have to get into this debate? This is a SOAP OPERA!
Suffice it to say that the odds of having a child with mental problems is very, very, very great in this case because the father and ALL THREE boys had mental illness. It wasn't just one person in the family-- it was THREE-- two siblings out of three-- and we don't even know if the sister has depression too.
So no, if I were Greenlee, I certainly wouldn't take the chance of bringing another human being into this world to suffer when the odds are overwhelmingly against a healthy child. At the very least, the two should have gotten genetic counseling.
And... Ryan continually said he didn't want children. He made no secret of that, but selfish Greens went and did it behind his back.
