Is there universal Good or it's all subjective?


(you can substitute him/his with her/hers wherever you like, no discrimination).

Most religions do say that there is universal good (in a moral aspect) and we should aim for it if we want to be truly happy.
And Yes I admit it's quite easy for a human brain to have aim, to have a line, to aim to reach the line and to keep it, aims are what we are all about afterall otherwise energy is wasted. It's really more convenient for me to have universal good. It's better that way. It keeps the balance.
Just imagine the three lines: upper is GOOD middle is NEUTRAL lower is BAD and it's a choice, if you want true happiness change yourself be good reach the good line, let's say more people live in a mix, good,netural, bad with fluctuations. Most are in neutral with variation of good and bad.
So if we go to the BAD line we can't feel happiness and so on.Here comes the question, is there some universal that we should aim for, is the upper line (GOOD) universal for every human being or every single indivdual on this Earth has his own GOOD/NEUTRAL/BAD lines in the brain which are formed differently and it depends on him.

Arguments that it's all subjective and it's all individual about the good/bad:

I'll look at humans as BRAINS.
Development of every single brain depends on internal and external factors. Internal are the individuality of the brain, neuron networks, its connections, dna, deep psychic, predisposals etc. external of course is the outer world which includes everything (environment, people etc.).
So how we form the perception of what's good and bad? We form everything because of the internal and external factors.

External are - from childhood we hear from parents,friends,media,religion, from wherever/whoever/whatever you can imagine we'll pick those things for the morality.

Interal are- Our own consciousness, we don't want to do something that we don't want to be done to ourselves. This is one thing that forms some part of our morality. Also we are effected from public reactions on our actions. For example, you kick somebody and just look at the crowds reactions comments etc. This is valid of every single ,,BAD,, thing you can think of. There are some other internals as well but I think you got the idea
Tadaa we have a morality. We do ,,GOOD,, we happy, we do ,,BAD,, we unhappy. ANd why? Cause deeply rooted in our brains is what is good what not and thus it makes us feel better or not etc.(or more complex thoughts of such variations). PLus if you do GOOD, you survive more, you are treated good from the society and we are social creatures etc. Reasons are many. And of course in this scenario where there are no universals we have all type of scenarios, where for exmaple some crazy wired brain feels good from doing stuff that the crowd considers as very BAD. He lies, he kills etc. and he feels good about it, cause his brain is individual and is wired in a such way that get true happiness from doing what's bad. But is that really possible?

Arguments that there is absolute universal GOOD.

I'm saying only GOOD, not universal BAD, not universal NETURAL(lol), just universal GOOD, the thing that you should reach to feel truly happy.
So, arguments are mostly of religious apsect, just take Christiany and Buddihsm for exmaple...
Most arguments come from my experience. The strange thing is that I've tried everything, I cleared my brain of many barries, I've cleared my brain of everything I could think of, and in the basics it seems that there is something I cannot override,reporgram, maniuplate.... There is something like inbuilt mechanism. This mechanism works in the following way:

WHen I do good(the universal one made up by religion), I feel good, I feel it right, it fills me with happiness for UNKNOWN REASON. Everything else is not the most right way.I can even do some actions or think some thoughts without prejudices and I feel very good about what I've done or thought.After that I ask myself, ok let me check according to the COMMUNITY where my actions and my thoughts go(in which category). I realzie that those things go to the UNIVERSAL CATEGORY of GOOD.
Universal GOOD is - don't lie, don't hurt anybody, help others,don't steal etc many other UNIVERSAL things you know them...)
And when I actually have in my head thoughts of (hatred,lust,anger etc etc etc etc Universal things as well) it feels selfdestructing.
So why? It feels like a natural PATH i should follow and I'm HAPPY? I think I'm cleared of all internal/external effects and still there is this PATH that my inbuilt mechanism needs to follow to be happy? Why why why?
Questions that arise: If there is UNIVERSAL GOOD, who THOUGHT OF IT? Is it just the way universe is? Who said that LIE is BAD and why when I LIE I feel BAD for absolutely UNKOWN REASONS ( I even reporgrammed my mind for a long time saying LIE is the best thing ,. it's individual, it's only me, only in my mind, it's what I learned by now, I have a choice, I can change it, I can LIE and be ok with it) NOPE, no matter what I BELIEVE and how I reprogrammed my mind the inbuilt mechanism still works and when i LIE i may not be feeling bad....but I'm definetely not feeling good EITHER! The best thing I think a brain can achieve(a ,,sick,, brain) is when somebody commits a murder, he can either feel neutral or feel phantom happiness but not real happiness. Basically those are my arguments that there is universal good which should be followed.

The Phantom Happiness and Real Happiness

Just to clear things out, there is ,,happiness,, that you might be able to feel even when doing all the universal BAD things.
You might feel happy when you KILL etc etc etc.(this is the case with the Killers, I think they Kill, they satisify their need and they THINK they feel HAPPY, truly happy, but I think it's the same happiness as to take your dosage of drugs, the as when you eat a lot, the same as you satisfy some basic needs, the same as you buy something new, such type of happiness, so when a serial killer kills he feels something like that but can never be truly happy). This for me and according to my theory is phantom happiness.
May be you also felt phantom happiness many times like: When you have a LOT OF MONEY, when you have POWER, when you have a lot of material things for exmaple, when you REVENGE etc etc etc. This is all phantom happiness and it's just a delusion.
True happiness? What is that? I think it has nothing to the with the MATERIAL WORLD, in none of the aspects of true happiness you can connect it anyhow with the material word. Secondly, let's just say it's something like when you feel LOVE(for whomever thinks he/she really felt it). It's something that you can use the word divine to try to describe it. It's very modest, it's quiet, it's silence, it's piece and at the same time full of energy, it's everything and nothing(no matter how cliche this may sound). Something that excludes all the charateristics of EGO (as commonly described).That's divine. And....I think that a killer cannot feel that, no matter how his individual brain is wired, I think that a person who does universal BAD THINGS cannot feel that, he/she can feel it after he/she changes may be, but not during or after the action of ,,evil,,.

So...please share your thoughts, find weak spots in my thoughts and share them as well....Thank you.
