Ron tried to discourage Eren from putting them in dangerous situations by giving him a grim possibility. And he considered the worst in his owner and came up with shallow deterrence.
"Haha! No need to nudge me in the "so-called" right direction, Ron. In case you forgot, I'm smarter than you. At least related to these things. You being my slaves now is proof of that.
I'll give you a hint to ease your mind. I want your help in dealing with a certain girl. It's not risky. And it should not put you in someone's crosshairs as long as you are careful."
Eren folded his hands after he said that. Something about dealing with a girl caught Dino's attention at last as his ears twitched in response to it. He couldn't help ask his owner about the girl:
"Who are we talking about?"
Eren saw the glint in Dino's eyes and smiled before shaking his head. He understood that the guy wanted to partake in his self-serving fantasies while not feeling any guilt in his consciousness.
A paragraph from Dungeons and Dragons wiki explains neutral evil aptly: A neutral evil character is typically selfish and has no qualms about turning on allies-of-the-moment, and usually makes allies primarily to further their own goals. A neutral evil character has no compunctions about harming others to get what they want, but neither will they go out of their way to cause carnage or mayhem when they see no direct benefit for themselves.
