Louis: More relationship with Carnivore

Louis despises carnivores for several reasons.

He grew up in the Black Market. Once he was adopted by Oguma, Louis found out that he was being raised in order to be eaten by carnivores. The thought that all his friends (which were basically his family) had been killed by carnivores bugs him a lot.

Carnivores are stronger. Louis resents the fact that carnivores are naturally stronger than herbivores. This is shown in the infamous 'bite me' scene, where Louis freaks out that Legoshi wont express himself in the demonic image that Louis has painted all carnivores to be. Louis is upset that he can easily be over powered by carnivores no matter how hard he trains.

There are more examples that follow this idea, but I'd rather not spoil anything.
