Good and Evil are concrete, and they are defined by the ruler of the Universe.............GOD. EVIL and GOOD are not defined by scientists and their “ends justifies the means” logic that defies GOD and his word. You are not GOD, you will never be GOD, and despite your research you will one day die and face the judgement of the ONE who is GOD.
You can stick your fingers in your ears and ignore GOD, but eventually you will come face to face with HIM.
Just remember Jesus died for you sins, and you CAN BE pardoned for your evil by accepting his free gift and letting him into your heart. But to do so, you must forgo your PRIDE.
Nobody is saying the ends justify the means, what I’m pointing out is that bad means DON’T automatically cause the ends to be bad. If we ever cure cancer the testing is almost certainly going to involve cultures that came from human embryos at some point, bad means to be certain but the cultures are there and WILL be used, and millions of lives could be saved. Using your bad absolutist logic anybody that takes that cancer cure is evil. Using real logic we can understand that getting those tissue samples that made those cultures was bad, but they can be USED for good now.
