When I finished reading these lyrics I clearly saw two meanings in it that mean to both lovers and soldiers. The first meaning of it is that it's clearly about soldiers meaning cadets AND generals going into war and some of them dying due to injuries caused by guns and some surrendering due too many people dying and suffering and going into comas. In a line it states 'Do you know what's worth fighting for? When it's not worth dying for.' This would mean that their asking them if they really think it's worth losing people and sacrificing themselves for something that really doesn't seem to be worth much. Now for the second meaning, for lovers that get heart broken this song clearly asks if dating someone is worth the heart break, for all you know and this is for the women, for all you know they could be players that would just fill their pleasurable desires and throw you away like trash. Now I don't wanna be sexist so now as for men you guys would date any girl you fall in love with but you don't know if she's a player or not. In all this song means a lot for all those who are heart broken and for our fighters out there that are still fighting to keep us all safe.

This is just my opinion. No one has to agree with this but this song has a strong meaning that they want to put out. In one of the verses one of them states that It's not alright, can you hear me crying? Clearly he's saying that he didn't wanna kill that person but had no choice because he was doing it for survival and self-defense because of feeling threatened or something. In another line where it states he would mean that he warned the person to step away or else but they didn't listen. So in total I think that this whole songs meaning is to tell others that they were doing it as survival and self-defense and didn't want to kill but they didn't want to be the one who dies or to lose someone so important to them.
