Situation ethics & natural law

(Original post by Starlight2000)
Situation ethics allows you to be flexible as it only asks you to do the most loving thing
Natural moral law is legalistic and is used in many religions. The problem with this is that once something like murder (the action) has been seen as immoral, to justify it you'd have to come up with a list of alternative rules to justify killing somebody to prove it was the most moral thing and also it stole the ability for us to make decisions without needing to look at a "rule book" to justify our decisions- Fletcher's key criticisms
Situation ethics allows you to do anything as long as it is the most loving thing like saving a woman by allowing her abortion. Natural moral law would say abortion should only be allowed under the doctrine of double effect whereby the death of the foetus was merely a consequence of say removing the uterus from a woman who has cancer of the uterus in order to stop it spreading but would not directly allow the foetus to be killed (the actual action)
Situation ethics, however flexible and better it is, has its own problems because you are told to do the most loving thing but aren't told how; people have different views on the most loving thing eg. Some people may agree on euthanasia as it ends suffering but others say it's simply giving up on one life and could potentially harm the lives of others. So in this sense, both nAtural moral law and situation ethics are similar and both came from religion originally
Hope this helped, however If you'd told the structure of the essay it may have been easier to help you as I, and I'm doing edexcel, have never and because of my board will never get a 'to what extent' q ( hope this made some sense as well)
