Didn't read whole article. Noted the sympathetic bias - how nice the parents are to kill their suffering baby.
What I wonder is in countries (or states) that allow euthanasia of suffering people, who draws the line, and where? I've had my share of suffering, suppose someone at one of those times decided I'd have been better off dead?
Oh, they draw the line at convicted murderers. Them, they want to live.
This is where the slippery slope begins, with the most extreme case. It's all downhill after that. This is how legalized abortion began, as well - extreme cases, life of the mother, etc. It's now a full blown genocide industry. May God have mercy on us!
