The Good trait falls flat. After the updates to the other traits, I hope this trait is updated.
The best way to improve the good trait is to have Sims with this trait get negative Moodlets from doing activities that are considered bad:
- Using Mischief
- Being Mean
- Hacking on the Computer
- Getting into fights
- Declaring enemies
- Cheating in a relationship
- Coming home from work in the criminal career, a villain in the Secret Agent career, or an Interstellar Smuggler in the Astronaut career
Also, good Sims should develop negative Sentiments towards Sims they catch doing bad activities such as:
- Being Mean
- Using Mischief
- Hacking on the Computer
- Swiping Objects
- Getting into fights
- Seeing Sims become enemies
- Cheating in a relationship
