I didn't like the movie but it made me think .

One guy started to take stuff from the dead ( a watch if I recall) while someone asked others to collect their wallets to deliver to their families.

This got me thinking about a similar scenario where survivors may ( or may not ) invade the dead for items that may help their survival. Say a Bic lighter or anything like that. Even their boots, coats or hats. Would you do it ?

In one scene , Liam Neeson forcibly stops a guy from looting a dead person, and later the dead person was eaten by the wolves. ( all items on him are gone) It makes you wonder if it was better in anyway to let the guy take what he wanted and maybe it proves useful later.
