<p>like you, adventurers are "sworn"to fight monsters, to gather fame (by leveling up and getting stronger) and wealth (through magic stone commerce), and to protect the people on the surface. bell's no diffrent he also kills countless monsters.
</p><p>this was mentioned in the novel but bell is protrayed as someone who can feel the pain of people through his own experience. and since he was attacked by goblin back at his native village, he knows monsters are dangerous and need to be dealt with, to protect people.
</p><p>that's why he can not go rogue or hold any kind of grudge or comtempt for people cuz he understand them
