This line sounds peculiar, I would appreciate your opinions (it uses the verb 許される)


First of all, to give you some context, there are 3 characters that will be
referred to as A, B, and C. The following lines are from a dialogue between A
and B about C. The character C has done things that are considered wrong,
unforgivable actually, and that's why in the dialogue there is 許される.

Character A does not approve of what C did. However, B is grateful; he is on
the side of C.  

> B: むしろ俺は感謝してるっスよ。  
> A: **許されることじゃねー** だろ。  
> B: **許される** って誰に？つーか…なんでそんな無下にできんスか？

I'm fairly certain that A is saying something like "But, it's unforgivable."  
"That sort thing shouldn't be allowed." (referring to C's actions)  
The subject are his actions, right? I say this because if A had wanted to say
"I can't forgive/allow/him for what he does", I believe (あいつを） **許せない** would
have worked or **許されない.**

Regarding B's line where he says 許されるって誰に？ if it sounds like he doesn't
approve of what A said, and given that he also quotes what he said (with the
use of って), personally I consider that it would have sounded better if B had
also negated the verb, as in, to say: "Unforgivable, you say? By whom?"

Would have made sense in my opinion and much easier to translate, but it's not
like that and I'm not sure what B is implying.

If Person A had said 許されないことだろ, this is true. But って is a quoting particle,
and what he actually said is 許される(ことじゃない), not 許されない.

Literally:

> A: 許されることじゃねーだろ。  
>  It's not something that's to be forgiven.
>
> B: 許されるって誰に？  
>  "Forgiven", by who?  
>  (implies "Regarding this matter, no one allows or disallows anything.")

I think English speakers won't say "Unforgiven by who?" in this context,
either.
