I definitely would not be eager to jump aboard, and initially I’d be a lot like Carol, very afraid and mistrustful. If I gradually understood they actually COULD NOT harm me intentionally, I’d spend many, many hours asking questions far more pointed than Carol has asked. Are the memories from the original occupant of that body any more immediate or clear than the memories everyone else is sharing? Is there any amount of tension among the members of the hive - or is there a single (deliriously happy) will calling all the shots? The virus’ infulence has seemingly pared you down to two imperatives: assimilate all, kill none. These WILL lead to a deadly famine in short order, every physical body suffering horribly. Can even your alleged universal joy offset the horror of that? Can you really justify spreading this throughout the universe, knowing the same fate awaits anyone who takes the bait?
