One of the biggest regrets when I was an UBF perpetrator was betraying I.A.S when she has done me no wrong.
Back when I first came to the El Camino UBF chapter in 2014 she actually came around the same time as me. I met her just prior to Sunday service. At the time she had long her before she was coerced into wacky training. I attempted to start a mundane conversation but she had no interest so I let her be.
Two years later in 2016 I did to her what I still regret even to this day: I betrayed her. This is how it happened. It was a Saturday night I had finished bible study (I believe it was Genesis Intensive). I was waiting for my mom to pick me up for it was 8:30 pm and there wasn't any buses running in Gardena. As I was waiting just outside the church I.A.S was backing out the driveway. She stop and asked for a ride. I was stunned for she had never spoken to me before. I declined the offer. The next day as I was waiting for a Gardena bus she passed by to go to her car and she waved, jumped, and smiled at me like some kind of psycho (no offence intended).
What I did next I deeply remorse even to this day. I betray her by sending a long (about 3-4 page) email to one of the seniors. As a result she got rebuked/punished. The reason why I did it was not to promote UBF's doctrine/dogma nor did I had nothing against her personally but that I figured that some one in the church will find out, tell my ex-bible teacher and he would get on my case and I would be blamed for the situation. For in 2015 I was literally rebuked/punished every single week for that entire year. I basically was only concerned about myself and my problems.
Some time later I apologized to her about what I did. She stayed away from me since and I don't blame her.
