In my own opinion money just became the center of the evil deeds of the people because we are living in the world where money is the only way to purchase goods and services, money became the man's center or source of happiness because it can give him a ticket to buy anything he wants, whatever he liked to do he can do with the use of money, greedy of the people also take them to the evil deeds. It is a sad but a truth that we are now need this money to be able to live, to be able to purchase our foods. Today, there's no free you need to purchase everything and that what makes people treat money as their God.
It's just that in modern human civilization, money is quite a universal equivalent, thanks to which you can get goods and services. It is much more convenient to engage not in the natural exchange of some items for others, but to introduce something that replaces all this. The idea turned out to be so convenient and productive that it conquered continents and states around the world and the economy is built on this. If there were no money in its current form, precious metals such as gold, which were the prototype of modern fiat money, were blamed with exactly the same success earlier.
