Welcome to the board.
You should attend the Memorial to see for yourself how JWs treat the ransom of Christ. You can pick up some of their other literature and learn more about their teachings as well. You can even arrange a Bible study with a JW member if you wish. You can do these things without committing to becoming a Witness.
But I'm afraid your inquisitive nature and independant spirit would not be welcome among JWs as they adhere to WT dogma as prescribed by the Governing Body of the religion. They allow no room for independent interpretations.
I wish you well on your journey to learn more about JWs. I hope you share your experiences with us as they proceed.
