Cans someone explain what voodoo is?

Is it a religion? Is it intended for good or for evil?

Answer here

Yes. Its devil worship. Its intended to harm others while achieving gain or wealth for the practitioner.

mostly to do with spirits as a voodoo person Wu say it's kind of their religion. it is witchcraft, and mostly meant for evil purpose.

Voodoo is a powerful mystical practice that can bring spectacular gifts and rewards to anyone who believes, who is willing to place his destiny in the hands of loving spirits, who await the call of service

Also called Verdun.

Based on the reading I've done about the Haitian variety, it's intended to help its practitioners lead better and more successful lives -- much like most other forms of religious faith.
