The Pāli word for death is “marana“.
However, I should have mentioned that “Māra” could have one of two meanings, depending on the context.
– One is Māra Devaputta, a Deva, who gave a lot of trouble to the Buddha because he was against people attaining Nibbana. His mindset is as follows: “Deva realms are so blissful. People should engage in good deeds and get rebirth in Deva realms.” He does not understand that he himself could be born in an apāya in the future.
– The other Māra is the “kilesa māra” referring to the defilements in a person’s mind. Those are temptations to engage in sensual pleasures. I think you could be referring to this second usage.
