They worshipped an evil spirit called Maboya
It was similar because African religion was based on the worship of ancestors of spirits both good and bad and the Kalinago worshiped their ancestors and nature and believed in evil spirits or as they call it (maboya) the second reason was that the west Africans believed that soul lives on so that the ancestors were always with you just like how the Kalinago believe that the spirit of their ancestors lived on after death to protect them and the Arawaks(Tainos) religious beliefs and songs were about spirits and ancestors and the life of the village.
