You make less sense as you go. The GC is irrelevant.
It is totally relevant.
Rape is a prohibited practice in war under the Geneva convention.
You don't think rape is immoral?
Not because of society, but because one can make objective arguments for it being immoral.
Regarding the OP, I'm simply saying that individuals who established pre-existing moral frameworks influence what people in general view as moral and immoral. If those moral frameworks didn't exist, then many people would be more likely to engage in immoral behaviors, such as murder. However, obviously, that isn't the case for everyone. As someone had to decide that murder was wrong to begin with, and get enough people to agree with them that laws were created to prohibit it.
Cool story.
Nobody's morals come from "themselves." They come from society, as you aptly describe here.
I'll leave you to your nonsensical argument. Good luck.
Not at all. People develop new morals which don't pre-exist in the society they were born into. Such as through reasoning. Societies are developed by groups of individuals to begin with, who used their own inner senses of right and wrong to create said societies, and are dynamic and constantly changing.
If not, then, naturally, slavery would have always been a norm, since no one would have been able to come up with objections to it on their own that didn't pre-exist in the society they were born into. Which plenty of people have, and can, such as via rational argumentation.
There is also evidence, for example, that some of our moral sentiments have roots in our genetics. Which may, in part, provide an explanation for that inner moral sense of right and wrong:
To conclude, it seems that genes responsible for the absorption of serotonin impact our moral decision-making process by impacting the way we interpret emotional events. With one gene variant making us more emotionally-charged in the decision-making process, it seems that genetic factors could go some way to explaining disagreements and conflict between people when making moral decisions that involve foreseen harm and utilitarian gains.
Researchers found that while parents can help encourage their children to develop into responsible, conscientious adults, there is an underlying genetic factor that influences these traits, as well.
