Sorry you lost this wonderful man.
Yes, there is no doubt he was awake. I think there are a lot of "brothers" (elders, CO's) that are fully aware of the dirty little secrets in the org.
My Dad was also an Elder and has passed away. He also would make interesting remarks about things. I just think some people just don't know where else to go and TTATT scares the hell out of them. There whole identity is wrapped around this organization.
Cherish the good memories! He seems like he was an awesome man and Dad.
