It's only natural to think for yourself, unless you're in a controlling religion. I was like you when I was a child too. One of the worst things I did was cave in and help my classmates carve a pumpkin at Halloween, and I prayed to be forgiven for over a year because I committed such a horrible mistake (I think I was in Grade 4).
You're brave to think for yourself! Continue on your journey. I was 16 when I started having doubts, and I waited 10 years to finally admit them to myself. In the meantime I was driving myself miserable trying to be a perfect JW, while still being mistreated by my JW "friends." Being an outcast amongst the Witnesses didn't stop once I became an adult. But now I have regular "worldly" friends who are super nice and normal! Wish I had left sooner.
