Interestingly, Glass's beef with Fitzgerald and Bridger isn't about them leaving him to die—it's about them taking his equipment and, most importantly, his gun. On one hand, this is a practical consideration: survival would be a lot easier with the help of a rifle and a knife. On the other hand, this is as personal as it gets. After all, Fitzgerald hasn't merely taken Glass's rifle—he's taken the love of his life.

Although the Rocky Mountain Fur Company is full of tough, rough-and-tumble men, they're as afraid of death as the rest of us. What's more, this quote from William Anderson shows that things are even worse when the person who dies is someone who you love.

In many ways, Glass's rifle, the Anstadt, is a symbolic representation of his skill and prowess. While many of the men employed by the Rocky Mountain Fur Company are inexperienced and unprepared, Glass has been developing the skills he'll need on the frontier his entire life.
