Of course not, unless of course they happen to be assholes. Tell them what you think they need to hear to make a terrible situation as bearable as possible and try to help them have a loving memory of you. Confessing your 'sins' on your deathbed just to ease your conscience without any thoughts of the consequences is an extremely selfish and narcissistic act which does nothing to help your loved ones.
My implication that I didn't effectively communicate was that they deserve to be with the True You in life, not just on your death bed. It's not about easing your conscience. It's about giving people the feedback that they need to be fulfilled humans!
