Cruel

Cruel is a Fatal Flaw featured in The Sims Medieval. It conflicts with the Good trait. 
It was confirmed in The Sims Townhall event. It may be similar to the evil or hot-headed traits from The Sims 3.
Cruel Sims have a lot of pent-up anger and disdain towards the world, and they often feel the need to vent their rage on other Sims.
==Attributes==
* Cruel Sims can start Fistfights with any other Sim, regardless of their relationship.
*Sims will gain the Pent up anger debuff every 12 to 24 hours, which degrades the Sim's focus by 20 points. 
This can be removed by any Mean interaction, like Argue or Spit in Face, or using the Trait interaction, Release Anger, at the cost of a relationship drop. Using the interaction Apologize will quickly repair the damage done to the relationship though.
