I think JWs "ignore" the way they do is because the WTS discourages them from thinking about Jesus in any capacity other than "King of the Invisible Kingdom".
It's almost like they're thinking "We can't see him, so he can't see us" the way toddlers cover their eyes when they think they're hiding.
By concentrating on OT "Jehovah's" qualities, they take away from NT "Jesus' " qualities.... the ones about wanting "mercy and not sacrifice", the ones about "love your neighbour as yourself", the ones about forgiveness and kindness.
