The omission of good is no less reprehensible than the commission of evil.

There are sins of omission and sins of commission, my friend. I've dealt with mine and i've forgiven myself... you should do the same.

The 9/11 Omission: Did the Commission Get it Wrong?

Evil is not something superhuman, it's something less than human.

Sins of ignorance or infirmity are to be admonished in a different way than intentional sins of malice of intention. The assurance of forgiveness is not to be offered carelessly by those whose conscience is seared, but to penitents who come contritely to the table of the Lord.

Let us carefully observe those good qualities wherein our enemies excel us; and endeavor to excel them, by avoiding what is faulty, and imitating what is excellent in them.
