I believe the correct response to your question would would be the third option, "Who has not, a hundred times, found himself committing a vile or a silly action, for no other reason that because he knows he should not?" as it shows how the narrator expresses how he feels about the situation, and why he did what he did. By saying this, he seeks pity from the reader.
