In conjunction with the KO vs. kill system mentioned a few days ago, I’d also like to see that killing has (negative) consequences on the character’s psyche (after all, he’s not killing monstrous orcs).
Thus there could be a meter for his Morale, separate from the character’s Reputation.
morale (noun) : 1. The confidence, enthusiasm, and discipline of a person or group at a particular time (Oxford dictionaries); 2. The level of individual psychological well-being based on such factors as a sense of purpose and confidence in the future (Merriam-Webster).
Morale could then affect both combat effectiveness (Strength, Agility) and dialogue options (Charisma), whereas Reputation would affect only dialogue options (Charisma).
Thus, for example, a thief with low Morale could still have a good Reputation and win people’s favor.
Moreover, confession to a priest could give a boost to Morale, as well as other actions like eating, sleeping, completing certain quests etc.
What say you?
