I'd like to straighten something out quickly. Just because Bravery as a skill doesn't exist in a character doesn't mean they aren't brave.  Sakara Kintoki doesn't have Bravery but nobody would argue he isn't brave. The same applies here, just because someone has Bravery stolen from them doesn't mean they suddenly become cowards or lose the ability to be brave. It just means they no longer get the bonuses to melee and resisting mental effects from the skill Bravery, instead Arsene does. And just because Arsene steals a skill that is directly connected to personality doesn't mean he suddenly gains that personality trait that was stolen. Let's just say for hypothetical purposes that Arsene is a massive coward. He isn't,  but let's just say he is for the moment. If Arsene were to steal the skill Bravery, he doesn't suddenly just become brave, he just gains the benefits of the skill.

And of course like Reflection has stated, if it really is such a big deal for certain opponents, just make it so I'm not fighting said person. Have me fight someone else. You are the GM in a PVE campaign, you control the encounters ultimately.
