Sims who Dislike Mischief Autonomously do Mischief

Yep, this has been a problem forever. I can make it so my sim dislikes mischief, potty humor, malicious interactions, pranks, deception, silly behavior and jokes.. and they'll still autonomously try to use those interactions and then get disgusted, angry or embarrassed by their own actions.   

I mean, that does sort of happen to us all from time to time... Say or do the wrong thing and then feel stupid for doing so..  You could conclude that this is normal sim behavior emulating real life. But gameplay wise, mischief happens way, way too frequently, so most of us are choosing to use the "dislike that behavior" traits simply because we dont' want our sims performing them autonomously. 

Mischief is great if you want your sim to prank and can control that action. Mischief isn't fun if that's all your sim autonomously wants to do.
