Miztvos bein adam l’Makom are ONLY bein adam l’Makom.
Kol Yisroel Areivim Zeh Lozeh. If I am m’challel Shabbos, it negatively affects all Jews; we are part of one entity.
I would say that bein adam l’chaveiro is also bein adam l’makom and bein adam l’makom is also bein adam l’chaveiro. The difference is in a direct sense. The reason we can do teshuva on bein adam l’makom without askind mechila first from every Jew, I suppose, is because to the extent that the teshuva is effective, it removes the harm done to everyone else. It would also otherwise be impossible to do teshuvah on bein adam l’makom.
