Lyric discussion by ReActor 

I think saturnine is right. Thom said in the NME that this is kind of a scary song about a guy who will do anything, including commit murder, to protect his family. Whether or not Thom is approving or disapproving of this idea is not clear.

"What would I do to protect my family?" is a question a lot of people find hard to answer, and I think Thom isn't really trying to answer it in this song, but instead to convey the feeling of being absolutely sure.
