Kol Yisroel Areivim Zeh Lozeh. If I am m’challel Shabbos, it negatively affects all Jews; we are part of one entity.”
True, but ultimately a person can do teshuvah for chillul Shabbos. You are expressing an esoteric concept, that what one Jew does affects us all. In many respects you are right about that.But ultimately it is still a SIN against Hashem. The guy who eats treif does not have to go to everyone in town and say he’s sorry. If he steals from someone, however, he can try to atone, but until he returns the stolen object to the person whom he robbed and begs mechillah, he cannot get Hashem’s forgiveness.
