There are a lot of people, even kids, who may know the difference between angels and demons based on what they have been told. Angels are said to be the creatures that you can see in heaven. They are supposed to take good care of people while they are still on earth.
At the same time, angels are supposed to welcome people when they reach heaven. Demons, on the other hand, are the creatures that will encourage people to do evil. If people feel that they are going to do bad things, they are said to be “tempted” by demons to do things that they are not supposed to do.
Angels and demons are figures of Christianity. They are mentioned through Christianity's holy book of the Bible. Angels are seen as good. When they are depicted in books and movies, angels are seen as white, holy figures. They are used as a symbol for those who help people and spread love.
An angel can also be a person that has passed and transitioned into their spiritual form. Angels are related to God, while demons are related to the devil. Demons are bad. When they are portrayed in media, they are seen as red figures, with horns that show how evil they are.
