In the Jewish culture almost all sins are not god's concern. On Yom Kippur, the Day of Atonement, According to religious beliefe God passes judgement on all people, who will live and who will die. you can ask for forgivness and for god's mercy but the only sign that ensues is that you keep on living even after. that is of course symbolic, and The Mishna in the tractate of Yoma ( 8:9 ) tells us that "Sins between one man and his friend, Yom Kippur does not atone for until one appeases his friend."
In Judaism it is up to the individual to atone for his sins, unlike christianity, and it is up to the individual to correct his ways by making "Teshuva" which loosely translates as repenting, but it is not a one time, or once a year act, it is a life process of correcting oneself. you can repent even on your lasr breath.
