Jonas is starting questioning himself about this society. He knows they are unfair with everyone but he wants to make a change. After noticing that his friends didn't knew the real significance of war, he knew no one except The Giver would understand him, that's why he needed to make a change. The Giver showed Jonas what means being released and it means death. He watched his father killing a baby! The Giver told him about her daughter, Rosemary, who was the Receiver of memories and "failed", she couldn't handle anymore the memories of pain. Jonas has created a plan with The Giver, Jonas was going to scape to elsewhere which they are shire it's real.
Jonas wants to recover all what his society has lost because of the committee, he wants everyone to recover memories. I think it's not fair for everyone to be the same just because a little group of people decide it. "It's true that it has been this way for what it seems forever. But the memories tell us they it has not always been. People felt things once. You and I have been part of that, so we know." I think Jonas wants to be fair with everyone. Its not fair that some people are obsessed with sameness and because of that they changed everything. People are not able to make their own decisions, know they even kill people thinking that that is normal. It wasn't like this before and Jonas is the only one who took the risk to change this, I think he is a hero.
Jonas is going to change everything. He is the only one who is brave enough to take a risk. Jonas is a hero. Life is all about taking decisions and risks, people can't do that because they don't have memories. The committee has taking away their lives because they can't do that, they need memories and feelings. Memories are made to share them.
