906. Is it wrong for those who do good to be conscious of the goodness of their deed, and to acknowledge that goodness to themselves?
“Since human beings are aware of the bad they do, they must also be aware of the good they do as well. It is only by this recognition of their conscience that they can know whether they have done good or bad. By weighing all their actions according to God’s law, especially the law of justice, love and charity, they can decide whether they are good or bad, and can approve or disapprove of those actions accordingly. Therefore, it is not wrong to recognize the fact that they have triumphed over evil and rejoice in having done so, provided that this does not turn into narcissism, because that would be as reprehensible as any of the faults over which they have triumphed.” (See no. 919)
