Demons, led by Satan, care about human beings because they view them as rivals to their own spiritual rebellion against God. Demons are believed to seek to corrupt and lead humans away from God in an effort to diminish God's creation and thwart His divine plan. Since humans are made in God's image and have the potential for salvation, demons aim to tempt, deceive, and lead them into sin, hoping to separate them from God's love and grace. This spiritual conflict is seen as a constant battle between good and evil, with human souls being the prize.
