An idol worshipper can be grateful for being created, and acknowledges a superior being. Yet he is equated with a murderer. So Hammas, Hizbolah, etc. are associations of idol worshippers. The afterlife is learned from the written torah. It helps one understand when the good suffer.
Deniers lose their share of the afterlife, as punishment for false testimony is 'as they misled'.
Care for your body as the most special of material wealth entrusted to you. Help your fellow man. Preserve the environment. Unless a threat to the mother's life protect the sanctity of a fetus. Potential life and corpses should be treated with respect.
