As it seams that nobody reads the article and is just jumping to conclusions…

This child was born very prematurely, at only 26 weeks of gestation. It quickly became apparent that the child had suffered severe brain damage, resulting in severe cerebral palsy and a visual impairment. This was compounded by frequent and severe epileptic seizures, which were largely unresponsive to medication. This left the child restless and unable to sleep for long periods. They also had mucus in their lungs, which made breathing and swallowing very difficult. 

Given the cumulative effect of these conditions, it was clear that the child would not live to adulthood. The doctor also determined that their suffering could not be alleviated through medical treatment. The doctor and parents, therefore, decided to actively end the child’s life.

Now think about that. That is a child that was not supposed to be alive in the first place (26 weeks! A pregnancy is usually around 40 weeks). It is suffering. The most humane way forward (for the child) is to end it’s suffering.
