Christians aren't worshipping John. He was merely a tool used by God to speak God's word. Material goods are evil when it becomes all we care about. He is calling the world evil, because there is so much sin (murder, cheating, lying, etc.). God is supposed to be number one in our life, and right now, the things of the world are prioritized above Him. If you don't believe in Christianity, I won't condone you, but I do ask that you respect the fact that I do. Knocking down the Bible (and the people who wrote it) because it was written awhile ago just isn't going to help me see your perspective any better.
