WT will even distance believers from other believers to better serve the cult. Bethelites, missionaries, circuit workers, SKE pioneers, JW children ... all encouraged to leave home, leave jobs, leave believing family & friends to pursue greater "privileges" and "assignments" in the cult work.
WT wants to have the dominant relationship in your life. They word it as "putting God first", or "seeking the kingdom first"... but in reality, all that terminology means is Watch Tower first.
