The devaluation of life occurs when men are no longer persuaded that man is made in God's image. This mindset/presuppostion trickles down into legislation (legalizing abortion, doctor assisted suicide) and even into the individuals attitude towards their own life.
When the society or the individual is convinced life has little value, they act accordingly.
Claim: Devaluation of life occurs when men are no longer persuaded that man is made in God's image, which leads to abortion and assisted suicide.
Rebuttal 1: Assisted suicide to avoid pain and suffering from terminal illness does not stem from devaluation of life. This is because people who do kill themselves when they're suffering terminal illness DO value their life - but if they're going to die, they may as well die without suffering.
Rebuttal 2: Many people who have abortions believe man is made in God's image. The issue stems from whether or not a FETUS holds the same value as a living person. When is a fetus no longer a fetus? When is it considered living? People who are okay with abortion most often view the fetus as non-human or as a lesser human. This is all debatable, but none of this has to do with the idea man is made in God's image since you'll find many non-Christians who feel abortion is wrong too.
Is a fetus a human and does a fetus deserve the same rights as those who have been born? This is the question - it has nothing to do with the image of God.
When the society or the individual is convinced life has little value, they act accordingly.
I already stated how abortion isn't based on the devaluation of life, but whether or not a fetus carries the characteristics necessary to grant them equal rights as those who have been born. This is why people who support abortion still oppose the idea that babies be put to death, because a baby isn't the same as a fetus. If what you said is true, then pro-choice advocates would also argue that babies have no value. That's not the case.
And again, assisted suicide doesn't occur because people don't value their own life. If you're about to live the rest of you life in immense pain and agony before you die, then you may feel it's better to die before the pain and suffering begins to take over. You can argue that this person values a life of pain and suffering less than a life of happiness, but that's a key distinction that must be made! You can't simply say people devalue life, therefore assisted suicide and abortion. You have to look at the actual standards people hold.
If your child is sick and you refuse to take him to the doctor, despite his serious illness, does that mean you devalue his life? If you answered yes, then does it also mean you devalue an elderly man's life because he doesnt want to live on life support? If you answered yes to both questions, then what you're suggesting is that we should keep people who are in pain alive for as long as possible - even if it makes them miserable. If you answered yes to the first question and no to the second question, why? After answering why, did you realize we base the value of life on differing standards?
Most importantly, assisted suicide is consensual. Otherwise it's murder. This is a very important distinction that must be made. Everyone keeps talking about how assisted suicide will lead to euthanasia, when there's literally zero evidence for it. That's like saying self defense leads to mass murder. You take two scenarios with only a few similarities and conclude one must therefore lead to the other. And heck, what if we used this logic in politics? This is how we end up with overbearing regulations, because if we allow one thing it might turn into something else - therefore ban everything!
