Many Buddhist are not Sotapanna hence they still have the self-view. They think what Buddha taught wat that the same person is re-born. Buddha never said the same person is re-born. What he taught was the Dependent Origination. Our action has a result. (kamma and Vipaka) Once you understand Dependent Origination you can accept the Kamma and Re-birth. Buddhist Kamma and re-birth is not the same as what is taught in Hinduism. Some Buddhist think that the Buddhist teaching of Kamma and rebirth is the same d Hinduism.
