Will halloween( Festival of the dead) be harmful to?

The issues that you have brought up can be handled if we understand that the children that are being effected this way are in need of A) Love so they don't see this as a way to attention grab. B) Discipline and a moral comp so that they can see this as just entertainment and not reality. C) Teachers and Doctors better trained to spot mental illness in children before it gets too far, so that the children who cannot tell reality from fiction can get help before they cross the line. So instead of complaining about what this piece of entertainment might do to children it would be far better of you to find ways to support the children to become the reasonable, healthy, responsible adults that they will need to be to get by in the world.
