Evil is the absence of God. If Harry Potter and D&D really did teach people witchcraft or led to the occult, then I would agree with you. But it simply doesn't and any claim that says it does, comes from those who do not know what it is that they are talking about. Sorry if that sounds a little to blunt.
Evil is the absence of God, not quite right, evil is not doing God's will not obeying God's commands.
Everyone will be judged according to 'The Word', God's commands.
I think you are missing the point my friend, I say that in His Love. Harry Potter is a character in a book, he isn't directly teaching sorcery and witchcraft, sorcery and witchcraft is added into the story and the influence comes from what people see, what children see and believe.
In a previous post I included a number of replies to a Google search asking 'does harry potter include sorcery and magic'
Here is one of many statements regarding the question...
A letter from an ex witch says...
Sorcery and witchcraft are real. Although it is valid to clarify witchcraft vs. sorcery, whether Harry Potter is called a witch, wizard, or sorcerer is irrelevant when looking at the content of these books to determine if they are appropriate for young people. Sorcery is nothing less than the attempt to replace God,..
Harry's books are about a young 11-year-old generational wizard, Harry Potter, who attends the prestigious 1000-year-old occult boarding school, Hogwart's School of witchcraft and Wizardry. All his teachers are practicing occultists, and tutor their students in the dark arts of sorcery and divination: fortune telling, astrology, potion mixing, spell weaving and curse casting.
Above I read,
parents shouldn’t allow their children to read them. But would now add, should any truly born again Christian watch or read such things?
2 Kings 21:6 (NKJV)
Also he made his son pass through the fire, practiced soothsaying, used witchcraft, and consulted spiritists and mediums.
He did much evil in the sight of the LORD, to provoke Him to anger.
There are many verses in scripture that warn us of witchcrafts, wizardry, sorcery and such, notice above God was provoked to Anger!
If there is witchcraft, sorcery and the like in the book, then it carries that message, it includes that which God warns us of.
One drop of blood in a glass of pure water contaminates the water, witchcraft, sorcery and the like in a book contaminates the story.
I would not want to be responsible for saying to others, Harry Potter story is OK, there is nothing evil in it. I have to say, Harry Potter stories are not OK according to God as the stories do include sorcery and witchcraft, the stories are in effect therefore encouraging that which God warns us against.
The devil is the deceiver of souls, he dresses everything up to look good, but in effect are dragging people into the darkness, dragging people away from the Light of Christ.
Blessings
Peace be with you.
