You can't talk in any sort of overall terms... on the Elizabethan attitude to witchcraft... but we might, for instance, take as an example the attitude of James I... the king at the time that Macbeth was written... who himself had written a book before he was king of England... when he was still king of Scotland, about witchcraft, "Demonology"... in which he shows that he believed at that point in witchcraft.
