CMV When parents murder a disabled child it is justifiable homicide
From http://en.wikipedia.org/wiki/Justifiable_homicide

It differs from other forms of homicide in that, due to certain circumstances, the homicide is justified as preventing greater harm to innocents.

Families with disabled children suffer from poverty and stress. The parents are often forced to give up their careers to care for the disabled child.

The stress on the family due to a disabled child often results in suicides of the caregivers, http://www.disabilityscoop.com/2012/03/27/disability-advocates-parents-kill/15248/

Social supports don't reduce this stress but only spread it out to more people.

Raising disabled children's causes a great deal of stress, http://www.disabilityscoop.com/2009/11/10/autism-moms-stress/6121/

While the disabled child is innocent the burden of care can destroy the life of their parent. The life of the parent is more valuable to society than that of a disabled child because a parent can work and support themselves while a disabled child will be very unlikely to work or support themselves.
