The perfect example from this book that sometimes we're better off not knowing secrets is when Jonas discovers what his father's job actually is. His dad is what they call a Caregiver; that is, he nurtures infants until they are placed with families. When his father brings Gabriel home for extra attention, Jonas and the reader see his father as a truly caring person. Gabriel has been a difficult baby, and if he doesn't improve, he'll have to be released.
Then we find out exactly what it means to be released. Over closed-circuit television, Jonas watches as his own father "releases" an infant: he kills the baby with a lethal injection. Now Jonas knows that there is no "elsewhere" that unwanted or ill or elderly people are sent to. They are simply put to death.
