Ok, I need opinions on Halloween?

I am part of a christian church, and I have always celebrated halloween, just for fun. Never dressed up as a devil or anything. But, I am feeling really guilty about the decorations my kids are putting up. I don't want to take halloween away from them because I know that we are not partaking in evil. We just do it for fun. I was never held back from trick or treating as a kid, so I don't want to take that away from the kids. Honestly, is it a little extreme to say that Halloween is a devils holiday?
