Why Religion, the Ethical Life - Keeping the Atheists at a Distance?

It's not so much that "Universe has to have a purpose" but to think, by deep intuition by ethical living, that there's something there beyond a "simple, cold grave"! Besides, if this "cold grave" thinking leads people awry then what is the responsibility? At least with the soul people can speculate and have a hope in life. Why kill this hope? Why keep whining that people have "superfluous, unscientific" thoughts as if it's supposed to have merit? In short, what if the Atheists are d*mn wrong? At least ethical living will carry a lot positive with it in case the hope proves to be in vain...!

What I'm saying is that ethical living may lead to (better) after-life! If not only the good consequences of ethical living in this life, that is, both for society and family and friends and yourself, ethical living proves valuable (given that there may only be this "cold grave")!

The logic:
Prem. 1: Ethical living -> hope of (great) after-life "and possibly more, i.e., God/Heaven"
Prem. 2: If not (great) after-life -> ethical living -> Very good consequences in this life, society, family, friends, yourself
(Deduction)
Conclusion: Ethical living proves worthwhile in every respect!

What if ethical living proves crucial for all this hope in God or what if there's something fantastic in death by living ethically? What is the responsibility for those against this? It seems they risk very little by insisting on a "cold grave" and being "scientific" despite the very stories of the many Near-Death Experiences and Out-of-body experiences! Why do they bother if the answer isn't to spread the corrupt mind?

(By this, finally, I hope to shove all Atheists into Secular Humanism or Humanism with Atheism!)

Does immorality force one to reject Christianity?

Does immorality force one to reject Christianity? That the logic of the mind by one's lack of morality in "losing" one's soul by deep sins against humanity/nature causes one to reject God/Christianity...

Rejecting God can be the equivalent of embracing non-belief, Atheism, Satanism etc.

So, clearly when one has chosen a path of life outside ethics that qualify for God's grace and Heaven then all on the "outside" must be promising, also thrust a "scientific attack" against Christians for a "magical" thinking as well as displaying a "disbelief" of these propositions of religious belief, i.e., Heaven, God, stories of the Bible, the message of the Bible and so on...

So I see these alternatives for those outside faith:
1. To go on "crusade" against the faithful, the righteous... To wage arguments of chaos and hopelessness ("come, join me in immorality as there's no other way...").
2. To be silent and let life go on.
3. To oppose all life by all one's life and resources by hidden war against the goodness!
4. To enter Christianity in order to subvert/undermine Church and activities and goodness everywhere, to be a hypocrite!

What say you? Any logical soundness to this? Is this credible? A realistic description? Serious as it is!
