Well morality does not actually exist in the world, neither do ethics or values.
They are defined by society but remove society and you have nothing.
For instance, if there are only two people in the world and one says, “I am going to kill you”, and the other says, “ you can’t because it’s wrong”, what is he basing that off of?
There is no society with laws saying he cannot be killed, there is nothing written in the cosmos saying it’s wrong….nothing.
This is a misapprehension of the functionality of morality. You call it "society". I call it "any group".
Humans are social animals. Our very survival depends on cooperation with others. We do very badly in terms of survival when left to ourselves.
At bottom, morality is like "rules of conduct" in a social setting, meant to facilitate order and cooperation within the group, for the benefit of the group (and by extension the individual). In other words, in a social setting, one actually has selfish reasons to be moral and impose it on others to have them do the same.
A group, a tribe, a village, a society, an empire... can not survive without it.
Imagine the country you live in now. Imagine how it would be if literally all of morals and ethics would be thrown out.
Now, you can not trust ANYONE anymore. You can't even go and buy a sandwich because it could be poisoned. You can't start your car because it could be rigged to explode. You can't go outside because you could be kidnapped, raped, killed,...
Literally EVERYTHING you take for granted today would fall apart.
Morals are thus a
necessity for a thriving as a human dependend on a group / community / society.
And we see pretty much the same thing in EVERY social species. There are general "rules of conduct" in a pack of wolves also. And "immoral" wolves will literally be chased out of the pack. They will be "punished" for immoral behavior.
In social species, such social systems are inevitable and vital.
Atheists inherently have nothing to follow until they make it up. This is why we see their morality fluctuate all the time.
This is ridiculous. What I said above is true always. Regardless of gods existing or not. Regardless of having theistic beliefs or not.
No matter, social cohesion and cooperation is vital for our survival. And without morals (rules of conduct), there can be no social cohesion or cooperation. And then we will die. There would be no society. It would fall apart and disappear.
The reason morality changes over time (I guess that's what you mean by "fluctuate") is because the nature of society changes AND we also learn more about the world and about what works and what doesn't. Our "in groups" are expanding also due to ever-growing globalization. Wheter we like it or not.
Empathy plays a big role in this. Empathy is essentially the trait that made every society known to man come up with a variation of the golden rule (which, unlike what certain christians like to believe, is off course not at all exclusive nor original to christianity).
Believers have inherent morality which is consistent because it comes from God.
False. The morality of believers changes just like the morality of the rest of us. Because their world is also expanding. Their knowledge is also expanding.
It's just that in certain circles of believers, it changes more slowly because they are being "held back" by confusing moral reasoning with mere obedience to perceived authority. This is why, for example, many of them are still so homophobic. Because their perceived authority said it's wrong. That's why they believe it to be wrong. They have no actual reasonable moral argument to defend that position. Their "reasoning" is just limited to "
god said it, i believe it, that settles it".
That is more the morality of psychopaths then anything else. Psychopaths have a mental disorder that makes it very hard for them to engage in proper moral reasoning. In severe cases it makes it even impossible. So they rely on perceived authorities to
tell them what is and isn't moral.
Here's a little anecdote I like to share on this specific subject... It's actually an experimental test that allows to see which children have a tendency of psychopathy.
It concerns a classroom with children and the authority of the class teacher.
Scenario 1:
In general, children are not allowed to drink in the classroom during lessons. However this specific day is especially hot. The teacher says that by exception, the students are now allowed to drink as much water as they like during lessons. We then ask the students if in such a case, it is ok to drink in class. All children will say yes, it is okay.
Scenario 2:
In general, children are not allowed to fight. However this specific day there is a big epic boxing match, it's national news. The teacher says that by exception, on this special day the students are now allowed to punch their neighbour in the nose. We then ask the students if in such a case, it is ok to punch their neighbour in the nose. Virtually all children will immediatly recognize that there is something seriously wrong here. It is not okay - no matter what the teacher says. And most will in fact seriously question the sanity of the teacher. EXCEPT one specific type of kids. You can guess which. Those kids, will not see any problem. They will say "
the teacher said it is okay, that settles it."
