The Giver had to support Jonas in order to manipulate the future of the colony.
The Giver at first was just following the rules of his contract and doing his job. The giver needed to help Jonas get comfortable with receiving memories.
Jonas was just a little 11 yr old boy like his friend Asher and Fiona. Jonas shared his feelings at dinner and dreams at breakfast every day just like his friends. Jonas was a well taught educated boy who cared for the elderly like Fionna. Jonas had a mother father and sister like his classmates. Jonas was chosen to be the future giver because he had a sight called beyond the sight. Jonas was petrified with this knowledge. The elders made a mistake he did not have this sight.Jonas
