In accordance with Augustin, the reason that nor all obtain the happiness is because of the function between ' ' to want-merecer' '. As the will is something voluntary it man, that one deserves the happiness that lives in the straightness and the honesty, and, to live thus, only depends on our free-will, then, that one that it chooses to want to live in the straightness and honesty, will deserve happiness. One understands then that, for Saint Augustin (1995: 25), who practises the evil, suffers the evil, then, ' ' God must distribute rewards to the good ones, as well as punishment to maus' '. It is easy to understand such idea, therefore, when we have these four virtues, the act to practise each one of them is only through the will, however, we do not have to understand that the will is something bad and that in the trend to make a mistake, the will has its good side and this good side only can be fond through the choice, as the choice always is made by the man, then, the consequncias of such choices is responsibilities of the man, being thus, our life is dictated by the choices that we make. In these circumstances, when the person wants to choose good things, as she rewards, will have good things. If the person chooses for bad actions, it will have as rewards, bad things. The value of the merit of each thing, is proportional to the attitude that the person took to deserve it, thus, not if it can punish somebody of unjust form. One understands then that, in accordance with Augustin (1995: 61), our happiness depends on our good will, therefore: ' ' if for our good will we love and we hug this same good will, preferring it all the other things, whose conservation does not depend on our fondness, the consequence will be, as in them it indicates the reason, that our soul is endowed with all those virtues whose ownership constitutes in agreement life necessarily the straightness and the honesty. .
