What about this: If you decide to make a child then, you know that he will go to Hell or to Heaven right? No matter what, you still do it because you believe that you will teach him to take the right decisions for his life.

Great statement. Totally agree.

How can you tell what is the right decision? There is no right decision in life because every person thinks different, and if you think you took the right decision, someone else will think otherwise.

But here's a mistake in my opinion. Right or wrong - who has the right to claim what is right and what is wrong? The answer is obvious - the owner! Owner of some property decides what is allowed and what is forbidden. Isn't it? If you borrow a car from some person he'll tell you what you can and what you cannot do with his car. And that's how you can find the true answer what is right and what is wrong.

So when we consider our deeds towards somebody's property, we can understand what is right and what is wrong if the owner has given the terms of use. Therefore it's natural to put a question: "Who is the ultimate Owner of everything? Does such person exist? Who can say he owns everything?" And if such person exists we must obey his rules. So what is done against his will (rules) must be considered as wrong action. So simple, isn't it?
