Here are my opinions, for whatever they are worth. Feel free to tell me to take a running jump if you don't agree.
I would remove most of the occurrences of the word "that". IMO it weakens any phrase that (sic) doesn't need it.
Some of the words and phrasing seem harsh or rough on the ear, but maybe that's what you're after, considering the subject matter. If so, please do disregard anything I say intended to "smooth" it out.
For instance, the first line of the chorus ends with the word "killed" which doesn't feel musical to me. So I might try something like...
It's cold comfort to one who's facing death
To know he'll be avenged
Small solace to a man on fire
To see the building still standsWhile I didn't like "unsinged", this isn't really a lot better, but maybe it'll give you new ideas.
In the first verse, I might change the "or" to "and" in the 4th line. Then in the next four lines we see the word "sacrifice" twice. In the second line, one might possibly use "You gotta break a coupla eggs."
I actually have ideas for all the verses, but it's starting to look like I'm trying to take over your song!
So I'll stop here and give someone else a chance.
I like the topic a lot and feel what the song is expressing often myself. It's so hard to balance the detachment needed to make it possible to live one's life, with having compassion for others, especially on a global level.
I'll be looking forward to the next level of this song.
