Okay , I read all the texts and here is my point:
When humans first evolved as home sapiens , they had no morals , no virtues , no knowledge of what's right and what's wrong because what's pertaining to right may be wrong from someone else's point of view..They used to walk naked ,hunt animals , have no basic decency or even knowledge to operate themselves properly..Then came the religion, which told them what could be right and what could be wrong , it told them the right morals and virtues , generation by generation, the right morals were passed on like it must be practised, the religion ascertained them in following those morals not by their will but because it was compulsory.. Now-a-days, the same morals sounds so right because our mind is brainwashed in a good way generations by generations that the past practise has become the reality for humans
Understand it this way , if u were born as a child living in a household where your parents do evil things but reflect it as good , u would surely be brainwashed into thinking that what your parents are doing isn't evil but good..Good and evil is decided by the environment and that environment was set by THAT RELIGION long ago..If there was no religion, there would be no morals and virtues.
Another prime example is the 72 hoor theory , I am not talking about the whole community but a specific group , they are taught that u will get 72 hoor in your afterlife if u kill people not believing in your religion or doing something against it , even little children are brainwashed into thinking this way and as a result , when as a adult ,they are asked( why did u do it? ) they consider it a foolish question because what they did was purely Good and kind because they were brainwashed into thinking that way
