KH would have projected the "worst case scenario" and his SC too would have advised him. He carries only 3 charges (or convictions) and I have not seen anyone convicted for CBT being imprisoned for 10 years. So we're looking at 6 - 8 years max, but 3 - 5 being the norm.
At this point, KH die die must NOT admit guilt. As long as KH continues to claim innocence, the conviction will be construed as "trials and tribulations" among his trusted followers. After all, Jesus was convicted by both the religious court and Roman court, and KH would be quick to draw a parallel.
SH is now the anointed one to preserve the remnant of followers in CHC, and as long as there is not mass exodus from CHC, KH will return from Changi an even more powerful preacher. KH will have more to talk about the cocks and bulls in prison and his holy interactions with God in the darkest of hours, just as St. Paul and Silas did when they both were imprisoned.
I fully expect SH to tone down and start behaving more like a priestess than a geisha after the sentencing is done.
