Some random thoughts:
"ATTENTION! There is no lifeguard on duty in the gene pool"
You can talk revenge and retribution all you want, but it won't help that little girl. Mental illness is sickness.
In western society, we protect our members who ail and help them recover if they can and adapt if they fail to make a full recovery. Others are just sheltered and helped along so that they too may be "productive" members of society. In doing so, we have accepted the consequences that some of these persons may pass on their condition to their children. I suppose within a few years, some legislator will come up with a bill for genetic screening to ensure hazardous genetic conditions are not passed on to future generations. Then the comparisons to A. Hitler will start.
Where do we draw the line? Do we look at some persons and say,"I'm sorry. Your child, if conceived/born, will be a detriment to society?" That sort of thinking goes against so much of what we have been taught. I do not wish to sit in judgement.
