The illogic, immaturity and pure absurdity of your post is utterly amazing. The stupidity of the same is astounding.
First, in speaking to atheist who do not believe in a supreme being one might further realize that they do not believe in an "anti-god" (i.e., the devil, Satan, shaytan, etc.) either.
Secondly, there is no "judgmental" god as Judaism, Christianity and Islam believe or as any other religion might preach, profess or "teach".
Third, when appealing to person who more than likely attempt to apply logic and reason to their lives, your attempt to shock or frighten them will not work. In fact, it will have the direct opposite effect and, as they walk away from you laughing at you (not with you) you will be ignored as a waste of one's time.
The subjectivity you express is much more a reflection of yourself than of any objective reality. You see "evil" within yourself and you project the same and impose such into your view of the real world without having the common sense to realize you are doing the same.
The One God/Universal Energy that enlivens, fills and creates all that exist as an expression of love neither judges nor excludes, is neither good nor bad (nor any other subjective judgment and/or limitation you may try to impose upon the Limitless), is incorporeal as the voiveless Voice that sang all into being.
Although manifest in all things, it assumes the nature of nothing. It does not incarnate, it does not speak and its revelations are not presented in a manner that excludes, is not delivered to a "chosen people" (possibly the mental display of the vastness of pure human ego), does not speak in only one language of any human tribe, society or culture. Rather the "book" of the One is the lived life experience of all.
Please, awaken to the realization that the god you profess and teach harms many, excludes many and simply leads to the greater suffering of all that exist and such is not the nature of the One.
Please awaken to the realization that each must live in harmony with the universal energy in the spirit of love, kindness and compassion for all as all are one.
My foolish and so short sighted friend, please, learn the difference between hate and love and practice love.
one's vision, One's understanding, One's prayer and hope for all.
