Plans don't survive first contact with the enemy, and usually the reason someone has to make the call to make the ultimate sacrifice is because the plan went haywire somewhere along the line. Don't be so naive as to think things will go according to plan every time, nor that you will always have the time to retreat with everyone alive and come back to try again.

Being aware of that such a thing can happen, despite your best efforts, and still being willing to go out and carry out those plans despite the risk of it going haywire is the kind of thing that has been on display, and the situations surrounding characters like Louisoux, Moenbryda, and Haurchefant (we, as I've said before, don't know enough about Minfilia's events to accurately judge it like you're so fond of doing) fall into that category. I don't know how many times I have to type that out before you realize that I'm not saying they should expect or be required to die, simply to be prepared for it and not go through character assassination when they do.

But yeah, I get it - any form of sacrifice to you is a complete waste, and from other comments individualism is preferable to existence.

I'm done debating this, because again you all drag it back to "sacrifice is always wrong" instead of what I tried to do in starting a discussion about what else might have happened to Minfilia and the repercussions of those interpretations. You're not interested in that, you just want a soapbox to complain about your mancat pet again.
