My objective for going corps:  to serve God and help others 
Twi's objective for training:  follow the master trainer, till death 
Four years of twi leadership critiquing, reporting, reproving, screening, screaming, manipulating, etc.....extreme spiritual abuse used to "train" way corps. 
Physically, mentally, psychologically, socially, spiritually......challenges and barriers were set in place. Over-the-top assignments to intimidate and overpower.....like, get aerobic points and be at 5:20 am m
