From the article: “"If any other family member had a terminal diagnosis, there's no other circumstance where we would say, 'You know what, we should just kill them now; they don't have a chance for a meaningful life,' " said Dr. Ingrid Skop, an OB-GYN with the American Association of Pro-Life Obstetricians and Gynecologists. "And yet we do this with a fetus with a terminal diagnosis."
There’s a difference between a person with a terminal diagnosis and a fetus with terminal diagnosis: a fetus with terminal diagnosis probably is missing some very important body part, unlike an adult. You can’t really compare the quality of life of a being that’s missing half its brain with someone who has a mostly functioning body succumbing to disease. Moreover, who is to say euthanasia is wrong? Animals are put to sleep all the time to end their suffering, but for whatever reason, we force people to go through years of suffering. I’m not saying we should kill terminal patients, but simply leave it as a personal decision.
