We did murder some men, who were comrades to her or even possible friends to her. Furthermore all this was done by buy, whom she had crush on.
Arlin didn't kill anyone, and he wasn't the one making decisions. It would be blaming him for a situation that was essentially out of his control. A guilt by association with us. Not to say that these things don't exist, but the more reasonable the individual, the weaker their effect seems to be.
It was somewhat the same with Rin. While we lead our band of Theseuses to her doorstep and killed plenty of her teachers in the course of our expedition as is expected during a war, we didn't really do anything to harm her explicitly, or something that she would consider an unforgivable atrocity. We weren't even responsible for the death of her father. It was why - while still antagonistic to humans - she wasn't too keen on pursuing a personal vendetta with us, and by now she has become our partner, someone we (supposedly?) trust to watch our back.
No matter what his intentions were and how he saved her, Arlin still willfully lead a demons to her camp
Nope. Rin knew perfectly fine where their camp is, and Arlin did nothing to make her job easier. That's the truth of the matter. He didn't sneak her in at night, she walked right inside their camp and demanded them to submit or die.
I know, feels were hurt in the process, but everything that happened is hardly the boy's fault.
In my experience people are often judged based on where does their action lead on rather than what those intentions were.
Well, what did Arlin's actions lead to? Remove him from the equation, and you won't find a much different picture.
While Tenia regards us as enemies, or at least the 'bad guys', the worst of Arlin's sins is that he found himself in our service, not in doing them any active harm.
Actually, what I want to achieve through Arlin is to convince Tenia that we aren't
really the bad guys. I mean, if Rin knocked her mother prone in a single blow, she could have just as easily cleft her in half. Tenia's own fate, likewise, could be much worse. Yet we let them live despite them technically being enemies. Maybe we can be reasoned with.
I still hope to snatch an employee from the Cloakies. Fortunio is a decent pawn, but the Queen sounds like a much better commander.
I grant you it sounds more noble, but betrayal is betrayal.
Especially in crushed young maidens heart.
Well. It is now Arlin's job to mend it. I have faith in him.
Talking things through isn't going to solve anything between them and is for chumps, anyway.
Like explaining the situation to Rin back when we first met her in the new world never established an understanding between us.
In the end, it doesn't set him up for success (personally, I want Erdrick to take pride in his wards' successes) and it doesn't keep the girl docile. If Arlin had latent pimp potential, why aren't we using it to our advantage. [...] Either give him good advice (A)
Oh, but we are using it to our advantage. The boy has more success than we do. How many heads have we turned in the last week? Erdrick's whole problem is that he thinks A might be a good advice.
