In order to be effectively good, you must become a specific good and not a general one. You might content yourself with being conventionally good, which is keeping the common law and observing the customs current in your community, and otherwise enjoying life as you can. This will not be enough in times of turmoil, when you will need to be woken from your slumber.
Leaving the middling good aside, society (civilisation) needs a few people who take on themselves something more. It is these who are the counterweight to the minority who are wicked. Those pulling their weight may be fired by outrage at injustice or blatant lies, thereby turning a hurtful emotion into a force for good. Exactly what good is is undefinable, but can be recognised by the flourishing of a great (tho not unlimited) variety. It may otherwise be described as the absence of evil, but caution is advised in attributing evil since often it is confused with extreme weakness whether of reflection, resolve or knowledge.
Note the contrary, selfish, principle, often advocated, that one should indulge the wrongdoing of others in order not to poison one’s soul with unclean thoughts.
Society needs some people who commit themselves by character to serving a particular good, which may clash with other goods. Once first youth past, they commit themselves by identifying with whatever they are drawn to. It might be justice, which involves above-average observance of procedures as well as combatting bias. It might be the production of wealth, using inventiveness & initiative not only for oneself but for others, as with an entrepreneur. It might be the maintenance & restoration of health. Other proper focusses are truth in different manifestations. A novelist might seek to be true to life and humankind by inventing phantastical stories. A historian must endeavour to uncover what transpired in the past and not be led astray by the temptation to tell a good story. A journalist must inform with balance on all aspects of a matter, and not just those which their readership favors. You can reflect and find countless other avenues of character incarnate. Characters cannot be all the same. Heightened sensibility in one respect comes at the cost of diminished sensitivity in others. The most common differentiation is found between male & female perspectives and strengths.
Hence: There is no such thing as a Man for All Seasons.
There are however wimps for all seasons. These are people, sometimes in high office, who swap overnight one set of allegiances for another, as the lucrative door revolves.
Footnote: Common law is not the contrived law of politicians & lawyers. There is, for example, no moral injunction to declare taxable income tho there will usually be a prudential one. I’d go further and say that the common law as a moral injunction only applies where there are independent juries free of the direction of judges and where judges can be deselected by popular vote.
