Obviously, when someone dies, they will automatically know whether they are a ghost or an angel. However, while still living on this Earth, people may not know exactly what will happen to them in the afterlife or after they die. If it is true or believed that people become ghosts if they die a horrible violent death, then a person’s lifestyle could be analyzed.
For instance, someone who participates in violent crimes or is subjected to living in an area of violent crime may be more susceptible to a violence death. To be an angel, many people believe that they had to do good deeds on Earth. So, a person who does good deeds may be more likely to become an angel after death.
