Are there atheist ethics?

My conclusion is that each/any/every/all materialistic/atheistic/naturalistic moral/ethical concepts are immoral/unethical. There, is that enough synonyms? Just want to make sure I cover my bases.

How and why?

Because no materialistic/atheistic/naturalistic moral/ethical concepts provide justice and are therefore, themselves, unjust and are therefore, themselves, immoral/unethical.

But how can this be considering that many judicial systems in the here and now do, indeed, mete out justice?

Consider someone like Adolf Hitler: he enjoyed his power, he had hundreds of thousands of adoring adherents, he did as he pleased, when he pleased, to whom he pleased, and in the end—when he decided it was the end—he took his own life and then…then nothing. No judgment, no accountability no justice; only the sort of perfect peace of annihilation. Simply stated, he enjoyed his life, deeds and power and got away with slaughtering millions.

Now, consider someone more like you, like me: out of all of the very many dirty, rotten, stinking, illegal, immoral/unethical things I have done in my life I have only been called into account for a stunning minority of those doings. Surely we are dealing with 99.9% “got away with it” versus a negligible percentage of things for which we have been called to account, in whatever way.

Granted; two of atheism’s most popular and appealing consoling delusion are 1) the consoling delusion of lack of ultimate accountability and 2) the consoling delusion of absolute autonomy.
Why do you think that atheists are constantly going on and on about the fallacious nature of Judeo-Christian morality/ethics? They do not want it to be true, do not want to be held accountable and attempt to get others to agree with them as sinful rebellion loves company.
And yet, rejecting Judeo-Christian morality/ethics gets them to want to build materialistic/atheistic/naturalistic morality/ethics on the (so they think) discredited premise of Judeo-Christian morality/ethics (something for which they are nailed by Friedrich Nietzsche). Yet, what they end up building is unjust, immoral/unethical concepts.

In a chapter of his book Orthodoxy entitled “The Suicide of Thought” G. K. Chesterton noted:

But the new rebel is a Sceptic, and will not entirely trust anything…And the fact that he doubts everything really gets in his way when he wants to denounce anything. For all denunciation implies a moral doctrine of some kind; and the modern revolutionist doubts not only the institution he denounces, but the doctrine by which he denounces it…He curses the Sultan because Christian girls lose their virginity, and then curses Mrs. Grundy because they keep it…In his book on politics he attacks men for trampling on morality; in his book on ethics he attacks morality for trampling on men [find the full quote and its elucidation here]

Now, justice is one issue: Mother Theresa and Adolf Hitler end up the same way on the atheist view—worm food.
The other issue is one beyond anything that atheist could ever conceive: grace.

The concept of grace includes justice. We have sinned, we are guilty, we are accountable. Yet, Jesus has offered to take the accountability from us and upon Himself. Consider the disparity in the following video clip as both the atheist (my friend Michael) and the Christian (me) offer answers to a question about why would someone give their lives for someone else:

His answer is nonsensical to me and my answer is inconceivable to him. FYI: the entire debate can be viewed at this link.

So, you can make your choice: unjust, immoral/unethical materialism/atheism/naturalism or graceful Jesus.
