At any rate, it's been awhile, so I'll add my take and repost this post of mine:

The reason being because, again, I don't think people are taking all this in the right direction; everyone's listing various reasons how and why Miria made mistakes, but we have to remember Miria's intellect (which no doubt already took many of what we are saying probably into consideration), but more importantly, the fact that what she was doing wasn't motivated by strategy or logic, but by sheer force of will.
Miria did what she did because she wanted too, plain and simple, and we need to think about that; Galatea already implied that Miria herself was aware that what she was doing was probably suicidal, but she wanted to go anyway because she was so strong for what she believed. In these past two chapters, we examined how, logically, their is a mountain of reasons why this whole situation was stupid and not worth it....but again, what are the odds that Miria herself was aware of all this and decided to try it anyway?
Miria is not stupid; regardless of what happened in these past two chapters, we can't assume she suddenly lost her marbles or whatever; it's just that, what she did, was motivated by logic or strategy; on the surface, perhaps it is(Alicia and Beth being away for example), but their isn't much, and that makes sense: because she didn't go to Staff for those kinds of reasons. She went, purely on emotional reasons, because she felt so strongly that what she was doing was the right decision for the sake of her team.
She's like Claire and Deneve in these regards; acting out almost purely out of instinct and emotion, and, despite having a frosty exterior(and my own admittingly disliking opinions about her, because I wished she would have opened up more), she does have a heart and she does care for her team; she, obviously, wouldn't have sliced up her most loyal follower if she didn't have a good reason, and while we can argue about said-reason and say it doesn't make sense, it's stupid yadda yadda yadda....we have to remember that, said actions, and everything she did and done, was not motivated by logic and reasoning, it was done purely by emotion, force of will, and the belief that she was doing the best and right thing for the Ghosts.
In
that regard....Miria's death, is actually kind of beautiful; the way to Staff from Rabona is a looong distance, and along the way, Miria was probably mentally preparing herself for her likely death; she didn't want to die, obviously and no doubt, but the probability was very high and it's not like she knew everything that was waiting for her (and neither did we), but getting back to the point, as tragic as her death was....it was almost like a sacrifice she made for her teammates. We can argue that it was a needless and pointless sacrifice, but as I say, this whole scenario wasn't one motivated by logic and/or reasoning and shouldn't therefore be judged that way....she died, but she died, probably feeling the happiest she ever felt in her entire life; she sure smiled that way
.
At the very least, her sacrifice, will push the remaining Ghosts to fight even harder against the Organization; no doubt, without holding anything back.
Of course Galatea wouldn't fall for this. She has no back story! 
maybe I wasn't clear enough...
I wasn't saying people think it's great, just that it's nowhere near being super bad by consensus.
Since doing it to a character without a known past means he could do anything he wants and claimed it fit. Thats far from having a character develop naturally and attacking a known kink in there past. Most likely he'd introduce a past then attack it and that once again would be writing to effect a character in a certain way rather than letting them naturally develop and exploiting there character.
