そういう全てを含めて包み込む度量


> A「俺達の戦はもう終わったんだよ。それをいつまでもネチネチネチネチ京都の女かお前は」  
>  _Our fight has already ended. Stop being so persistent about it, what are
> you, a Kyoto girl?_  
>  B「バカか貴様は！京女だけでなく女子はみんなネチネチしている。 **そういう全てを含めて包み込む度量がないから** 貴様はモテないんだ」  
>  _Are you stupid? It's not only Kyoto girls that are persistent, every girl
> is like that. Precisely because you don't have the capacity to ??? you're
> not popular with them._

A scene between two former friends who are now busting each other's balls. The
bolded part is what I don't understand at all. I kind of managed to narrow
down the meaning of 包み込む here to what I **think** is another way to express
受け入れる but even then I really have no clue what that line is trying to get
across. Is person B saying that because person A is singling out 京都の女 from all
the others, he's unpopular? That doesn't make much sense to me.

よろしくお願いします！

Edit:

This line follows soon after when the person saying it wants to take over
control of the situation (she's depicted as a Chinese person and often speaks
broken Japanese):

> 善行でも悪行でもやるからには大将やるのが私のモットーよ  
>  _No matter if good deed or bad deed, I'll be the boss is what I always
> say._

^ is what I assume is being said but I'm not sure, the structure throws me
off, especially やるからには - I know that からには means ～だから、当然～だ as in
仕事を引き受けたからにはやり遂げないといけない。  
_Now that I've taken on the job, I'll have to see it through to the end._  
but it seems kind of out of context in the sentence given above. I've found a
source where やるからには is translated as _If I do..., then..._ but is that a
viable way to use this structure?




Yes this 包み込む can be translated as "to accept" (although there may be a better
verb...maybe "embrace"?). 度量 refers to the "capacity" or "breadth" of one's
mind. For example, a 度量の大きい(or 広い)人間 is a broad-minded person who is tolerant
of many things. そういう全て refers to all the negative traits every girl has (in
B's opinion) including ネチネチさ ("persistence", "unforgiveness").

> そういう全てを含めて包み込む度量がないから貴様はモテないんだ。  
>  You are unpopular with girls because you don't have enough mental capacity
> to accept everything (including the persistence of girls).

からには is a common construction, so please see
[this](https://jlptsensei.com/learn-japanese-
grammar/%E3%81%8B%E3%82%89%E3%81%AB%E3%81%AF-kara-niwa-meaning/). ~~But 大将やる
makes no sense to me. It should be a typo or a reflection of her broken
Japanese (I don't know if 大将 means something in a context like this in
Chinese).~~
