I will take a swing at it, for the fun of it.
If you argue that morality is intrinsic; then you are claiming:
1) moral values are universal
2) moral value do not change
Both claims are clearly not true as 1) different cultures have different background to morality e.g. when columbus or cortez landed in south america, the natives shared everything with him and themselves tried to help themselves to the westerner's goods. Well, sharing and stealing is easy to understand moralities; but here is the thing, the native american culture had no concept of personal procession, so how can they violate the morality of stealing if everything is shared? 2) morality do change over time, 4000 years ago, it is moral to own slaves; when slaves are considered as livestock; yet today it is not moral to withhold someone else's freedom but is still moral to own livestock.
So morality, at least in parts is acquired empirically just because we harmonize our perception of it with the society and time we are in.
For your fictional question on morality, I disagree and philosophers had also traditionally disagreed in the form of dilemma and paradoxes. I mean, who really feel amoral by killing pest like a cockroach? yet, most will consider killing amoral. Who felt bad for the zombies that movie hero kills, when we by all matrix can rate the fictional zombie figure as a living being that have limited intelligence; like a turtle or something. Who feels it is amoral to kill zombies? morality tells us it should be amoral.
Morality is intrinsic, so:
1) moral values are universal
2) moral value do not change
Truth is also intrinsic, so:
1) truth are universal
2) truth do not change
Let's see how we approach truth, we used to approach truth by conducting rituals, by using drugs and by sacrificing animals. Religion come along and we approach truth by referencing a book. Then there is this more recent invention called science, which is current mainstream method of approaching truth. Mostly, it is done by observation and experiment. The method we used to apprach truth changed over time. Our view on truth change over time. But does truth change over time? does theory of relativity not hold in ancient times? we disagree over truth, we fought each other over them, we debated each; nowaday we mostly just ignore each other and "entitled to an opinion", but are truth relative? so because I disagree with Einstein about time dialation and I am "entitled to an opinion", does time dialation disappear for me?
So, just because the humans changes over time doesn't mean truth changes over time. Just because humans disagree about what is true doesn't mean truth is relative.
Apply the same thing to morality and you're done.
What are you trying to prove?
Philosophy in its nature cannot be proven or dis-proven; It can only be reasoned with. A hypothesis or a theory can be proven or dis-proven. I cannot judge that if morality is getting better with time; I would reason that it only changes with time, better or not is a construct.
Philosophy in its nature cannot be proven. Science in its nature cannot be proven. Science, however, can be dis-proven. So can Philosophy.

I will show you a dilemma you just used. You wrote in the sense that giving money to help children in Africa is a good thing, a moral thing. But you also know that bringing the society out of poverty will also mean that there will be significant damage to the environment those people are residing in. So it is Amoral not to help people, it is Amoral to help people and allow them to damage the environment further; so which is moral?
No, by sharing some of my wealth with an african child, I do no significant harm to the environment. I was talking about current, already made wealth. I do not mention at all how I'm going to help developing the economy of african countries or if economical development
necessarily leads to environmental degradation.
What I presented are no moral dilemma at all. It's very clear cut what is the moral thing to do. There are true moral dilemmas, but chance are very slim that you and me is going to encouter them very often. our common every day moral problem is overwhelmingly with not following moral intuitions, not with having conflicting intuitions. Our moral intuition is not perfect, to find out what is the right thing to do sometime is not always straight-forward, but that's not the bottleneck here, the bottleneck is in
doing the right thing.
The thing is you are taking a perspective in presented in books about morality or ethics to be the gospel; the absolute truth. But inherently morality is a method of thought, a philiosiohy that is open to change and evolution. There is no right and wrong; all of that is in the perspective.
You must mistaken me to be a religious person. Where did I take morality out of which book? I advocate intuitive morality, the morality that your conscience whispers to you. You don't need any book to do that. About philosophy of morality, I did read books, but I don't take them to be gospel. I read their rationale, eviluate them and accept some of them. I do not need to reference any book to produce a critism on moral relativism, like I said, the reasons are obvious and easy to work through.
I suggest not leave too much morality to your thought, it was filled with pesudo-reasoning that your education filled you with in order to justfy the society you live in. If you want to rely on education, rely on logic and rational reasoning, then you would be able to see the breaks yourself.
If you're not interested in philosophy, like I said, you only need to rely on your moral intuition to be moral. It's not as simple as you think, you need to be humble and shake off the attitude that "I know the best", it's difficult for modern people and it requires practice.
There is no right or wrong? So, there is not one time in your life you felt shame? how about guilty? how about anger? Look at the figures you admire, do you admire them just because they are successful? Hitler is pretty successful too considering where he started. Re-read the stories you tresure, you love them because they show you a brighter world? a darker world? or a world that has justice? Sorry, I don't buy "all of that is in the perspective". If I'm perceiving, there is something that I perceive, my perception doesn't create the thing I perceive.
