Augustine: Learning

In his work, On the Free Choice of the Will, St. Augustine attempts to solve the problem of evil, as presented by Anselm, using the free will defense.  Augustine claims that God gave mankind freedom of will and the ability to use his will for good or for evil; however, he also claims that evil is not learned :  "Learning is good, therefore we do not learn evil." (page 1?)  I find this line of the argument problematic for a few reasons.  (Actually I find this sentence to be rather false).  First of all, St. Augustine believes that knowledge should and can very well support faith in God; and that all knowledge must be good, as it reflects the genius of an unsurpassable great and highest being.  But since evil is present in the world, as man uses God's gift of free will defectively, it would seem that some knowledge - that is - some things known to man are also defective; unreflective of the goodness of God.  For example, I would imagine it is quite apparent that hatred and prejudice are learned characteristics.  While prejudice is also truly a consequence of ignorance, I think it can be said that such blind hatred does not arise without particular ascertained conceptions of a group or of an individual.  These conceptions are often passed from person to person; from parent to child.  Granted that there can be such knowledge that is false and knowledge that is true, does it not follow that knowledge could either be reflecting God or not reflecting God?  Second, given what I’ve just made claim to, such knowledge that does not reflect the goodness of God might be used to create evil.  If man has access to knowledge, which can incite hatred or promote cruelty, then he is learning it or has learned it at some time.  Furthermore, man’s learning of something is (for Augustine) his interpretation of the eternal unchanging law of the universe.  Man uses reason to examine the content of his perceptions and to judge his own thoughts and actions throughout life.  But much of what man seeks to know about the universe is dependent upon his motivation for wanting specific knowledge.  If his motivation is to seek ways in which he can be more pious and more like God, then he will seek to learn knowledge that is good – knowledge that is reflective of God’s truth.  However, if man seeks to make evil upon the earth, then he will seek to learn knowledge that will fuel evil – knowledge that is Godless.  I suppose the problem with the falsification of the claim “Learning is good, therefore we do not learn evil” is founded in the possible implications this might have on his argument about free will.  If knowledge can be true or false, then I suppose we could say that learning can be bad and that we can learn evil.  Would these ideas I’ve examined lend themselves to criticizing Augustine’s claim that evil does not come from God?  More particularly, is mankind wholly responsible for his evil doings if evil is something learned?
