Justice and God

Some atheists use the injustice argument for atheism...
They will say that God cannot exist because there is no justice in the world, or if he does exist then he is some kind of sick, evil being who is cruel and unjust...(hence why they chose to be atheist, mostly do to spite and not real logic.)
may I ask where then did this sense of justice come from?

Justice and Morality are not from feelings or expectations
There is no sense to the idea that we all as humans should expect to be treated fair, and others to treat us as we treat them, without this idea of morality having a starting point.

The starting pointing is God. He puts order in the world. He created us to have a sense of morality and justice.

I believe that Justice and morality come from God. Assuming that everyone else has this since of justice and morality... where did it come form?...it came from God!
