Should mentally ill people have kids?

Everyone knows when it comes to mentally ill everyone suffers, families. Tax payers, the innocent working people and society. Why do we allow these people to pass on their defective gene's so that they can make more crazy people to stain our society? I mean you can't even force these people to take their meds. Hell, mentally ill people can't even take care of themselves and yet how can they even consider taking care of a new born! Yet this is why we have society to pick up the pieces of mentally ill people who go into the foster system with more problems and we wonder why society has so many problems. Women can't walk alone in the dark without having a good chance of being attacked or raped even killed.
