A wrongdoer is often a [person] who has left something undone, not always he that has done something.

-Marcus Aurelius

Another way of saying this is “There are sins of omisson and sins of commission.” Explain an example of the wrong done by someone who neglected or chose not to do something. Can “not doing” be as harmful as “doing”? Is it easier for “non-doers” to excuse themselves than “doers”? What kinds of personalities might choose leaving someting undone over doing something wrong?
