Hi,
In The Sims Evil/Mean traits are more about making the other sims angry.
Anger is the most frequent negative emotion caused by social interactions in The Sims 4.
Maybe a child should be more sensitive and react differently by being sad instead of angry, generally children feel more hurt than rage.
The Evil/Mean sims could enjoy/cause other negative emotions :
- Sadness
- Embarrassment
- Uncomfortable (Prank)
- Tensed ("I know your secret")
- Bored (Evil sim ruining someone's fun, for example by cheating at games)
Self-Assured trait and Confident emotion could counter the Mean interactions because Superheroes are stronger when they are confident.
Evil/Mean sim with Self-Assured/Confident could prevent any backfire.
