Just vs Injust.

I think we have all had an experience in which someone who is a malicious liar/thief gets ahead in life. We have seen them become such a popular person, because they hide who they really are around people. The person who always seem to do wrong things , always gets what they want out of life while the person who is living life in a just way gets nothing. It seems as if though life is easy when you are a two-faced backstabbing creep. However, you follow the rules and live your life helping people and you just seemed to get stepped on all the time. That same person who is getting ahead in life only looks out for themselves, not caring for the welfare of others yet people seem to love him/her. I never got this. I have seen it happen in my life over and over again, but then I realize I can sleep at night. The unjust person who is having life handed to him on a silver platter isn't happy inside. He is miserable, he needs to have people around him because the instant he is alone, he is reminded of his guilt and it starts to eat at him.
On page 49 it states, "Socrates develops his argument to the place where he concludes that the just person reaches the apex of human happiness, whereas the unjust person, exemplified in the tyrant, sinks to nadir of misery, using mock arithmetic, he concludes that the just person is 729 times happier than the unjust person." Even though the just person has to fight battles in order to get through life , and life comes hard to them, they have no guilt of being unjust which makes them not tormented like the unjust person. The just person is satisfied with themselves, the unjust person looks for way to expiate the guilt that he feels. Though things may be hard for the just person they are happier because they have a just soul and having a just soul and doing right in the eyes of God is the key thing in life.
