Ugh, yet another extremely kind, naive and way too forgiving mc. Clearly it is a world where are "dog eats dog" rules of survival.
You gotta be tough and have a strong mind, and not be too trusting towards others (the abilities that our mc has none of). You can see that the beastmen have learned that lesson the hard way.
Sigh, I have commented this type of a message many times before, and will do in the future.. But damn I dislike this type of a main character so much. Even that robot has more balls than him, since it was ready to end that slaver right there since it would've been totally justified.
