What alignment is 'For the greater Good'?

[Keltest]

But as discussed in this thread, this "lack of concern over the well being of others" would realistically be justified, including to oneself, by others having it coming on account of their own offenses, or being dirt to begin with, or being a necessary sacrifice so that more others can be saved, or being out of reach, or... It becomes a debate on whether these are comforting lies or unpleasant truths.

Being justified is not the same thing as being Good. That's where the phrase "necessary evil" comes from. "Lesser of two evils" also comes to mind. You are doing something evil because the alternative would be worse.
