What an odd thing it is that virtues can become vices when misused or misapplied. Of course, this is the story of the history of the world. What God has designed for good, man perverts to evil. Recently, Andy Nesalli has published some great articles on how various virtues can be exercised sinfully if we are not careful to tie them to truth and wisdom. I recommend these articles heartily to you and also to trace down the great compendium of resources that he cites or recommends within each article. Happy reading!
