Everyone - JW or not - is required by nature to make decisions on the basis of incomplete information, and we are 100% responsible for the decisions we make.
It doesn't seem fair. But since the rule applies to everybody, maybe it is.
Or maybe the guilt is meaningless. Maybe the idea of being 100% responsible for anything - good or bad - is an illusion.
I have a LOT of anger about the circumstances of my life. My parents were a couple of idiots who stumbled from one bad impulsive act to another.
When I really try to put myself in their places it seems almost like their bad choices were unavoidable, and I am only left with pity for both of them.
