They the JWs are so concerned that any credits goes to Jesus you'll automatically become a trinitarian. They then completely relegate Jesus as just a tool once an angel "Michael " to be used by God as a human sacrifice. For being willing to go along with being sacrificed he Michael gets to become king for awhile and that's about it. I realize this is a over simplification but it's pretty close to the truth.
They completely miss the piont that Jesus is elevated to god like status for what he did weather you believe in the trinity or not he still becomes a God!
