Being a good person seems to me mainly to be a matter of one’s whole outlook in life. Acting badly is a human inevitability, even if it stems from thoughtlessness and not malice, or from a momentary feeling and not a long habit. So, if one celebrated one’s errors – or just said “that’s the way I am; so be it” that might be what makes one bad. I wonder whether there are such people, who are so content with their wrongdoing that nothing in them resists it. But a single action seems less important than one’s response to it and one’s willingness to learn. Of course, our actions do matter and they tend to shape us.
