It's true that Casuality exist because Humans always want answers to every events in our lives

And we do believe that nothing happens without something influencing it

Yes, a lot of people do not believe in God, because they feel if he was such a loving father, then he shouldn't allow death, famine, hunger, wars, sicknesses to plague us.

Some even get bittered by the fact that the wicked ones seem to have the best lives as compared to the good folks

If only they could understand that life is a result of our actions. The wicked who seem to have the best lives, have something they believe in, and act upon, and the results is the extraordinary rewards that they received

The good folks should find their place in the world, believing in the benevolence of nature, and the abundance that it brings, then, find ways to key into it, through the good means, and then, they will find extraordinary rewards too

God isn't to be blame for the decisions that we make, because it is our decisions that alters what happens next
