As a JW, when I'd find out someone got disfellowshipped, I'd shake my head and think, "What a selfish person. Choosing immorality (it had to be immorality) over Jehovah. I hope I never make such bad choices." I felt sorry for their self-imposed position.
But da'd people were different. They deliberately turned their back on the gift Jehovah had given them. I figured anyone who da'd themselves had basically given the finger to the elders who I'm sure tried so hard and lovingly to keep them in the flock. They had to be insane!
To me disassociated people were practically inhuman to me. I couldn't imagine that many people just wanted to be left alone, and were forced into disassociation. I couldn't imagine that people could actually NOT believe it was "the truth".
