Fear of the Lord is the beginning of wisdom.
To fear anything else, especially demons and their bullshit, means you don't fear the Lord.
Why are demons more real to the fearful in this world than God himself?
I do not fear death. I do not fear evil. For the Lord is with me, his rod and his staff, they comfort me.
You shouldn't let anyone or anything make you fear. To fear or not to fear, and what to fear, that is your question and your choice.
