Yes everyone is free by law to follow their own individual believe systems.

But why is it hard for you to understand that this is a majority sunni Muslim country?

It's literally in the constitution.

Obviously school gonna adopt, teach and try to imprint Islamic values on the children of a Muslim country.

You don't like that, create your own private school that aligns with your own beliefs and remove it from curriculum.

On another note, you using psychology as an excuse let's me know two things.

You either have confirmation biased or you're just throwing words.

Religion can and is a useful tool to teach kids hard concepts like death in a simplified manner.

And is also very valuable to teach them right from wrong.

And you're acting like the teachers are telling the kids they're going to hell straight up where they'll be tortured for eternity outright.

I don't know what school y'all went to but from my own experience they teach you by stories good people who's kind, generous, patient, helpful are rewarded, bad people who're greedy, liars, abusive gets punished simple as that.

Last I checked that's a good thing.

And last note: when it's about religion it's indoctrination but when it's anti religion (that's what you are, a normal athiests believe in science and minds their business) it's freedom of choice which is hypocrisy. 

Freedom of religion yes. But
