I'm pretty sure this song is about depression and suicide. The artist is saying that It all gets us at one point and theres no use hiding from it. With it constantly flushing out happiness people have to put on masks to make people around them thing they're happy. He is saying that he won't give up on anyone until they "close cold eyes" meaning they're dead. He also seems to be personifying depression as a murder because of all the lives it takes.
