God also cursed man to toil the earth; therefore tractors are immoral.
The argument is stupid. Pain meds in labor don't make labor less traumatic, and using a tractor doesn't mean you've "cheated" your punishment. It's still damned hard in both cases.
I second your post. If a person knew the time, maintenance and money that goes into tractors that farmers use and you were the farmer, you would not necessarily think it made your life easier. It brings it's own set of problems.
Same goes for women in labor. One should consider that the meds dont work for everyone and There is still the pain from after the birth, exhaustion, mental effects, possible hormonal imbalance, etc. Pain meds sont do anything for that. Secondly, what about Charity? A charitable thing to do is "comfort the afflicted" and "comfort the sorrowful" . One has a certain amount of duty to relieve pain if it is reasonably possible.
If ignoring the Corporal Works of Mercy is a moral thing to do, then by all means, dont take anything for your migrain. Sick? Dont go to the doctor, of any kind. Since pain is a consequence of sin - a curse, you may as well not eat when you are hungry because it would be a sin to relieve your aching belly. But then we have the problem of not eating being suicide which is also a sin... you see the problem?
