Are yu gi oh cards evil?

Answer 1

There is no Yu-Gi-Oh card called 'Who is God or Evil'. I suspect it may be a fake card with an incorrect english translation, or a card that got a completely different english name unrelated to its original Japanese one.

Answer 2

Some people speculate they may be, seem, or act "demonic", based on the cards and TV series:

• Use 'magical' Spells (Cards) (possibly Black Magic)
• Some monsters are (grotesquely) demonic (more so the original artworks; a good handful of cards have been redrawn for American standards)
• Some cards can only have their full powers attained through a chant
• Different types of cards, like Ritual Spells, Fiend, Spellcaster, even Zombie types
• Winning a duel can steal the loser's soul
• Certain characters have "evil" transformations, or at least become someone else, like possessed (Yugi -> Yami, Marik, Bakura, Shadow Hunters (possessed by Marik))
• Cards can come to life (Lava Golem torturing Joey)
• etc.

As long as you don't believe anything or worship the cards, they are not naturally evil.
