Heroic Problems

An example i think of is from the video game The Last of Us.  In the video game it is a post-apocalyptic earth where zombies run around and the last of the human race try to live and survive.  The main characters are Joel, an older man, and Ellie, a young girl who is not his daughter.  In order to survive the world the duo have to kill zombies and looters alike.  Ellie is immune to the disease and the plot is taking her from Boston to Colorado to scientists who will use her as the cure.  In the game the player becomes very emotionally attached to both characters and we seem them as the heroes of the story to save mankind.  Also not to mention they are both badass characters who can kill, but also have a very sensitive side to them.  Both do terrible things though and kill and murder other humans.  Though in the end, Ellie has to die in order for the scientists to extract the cure from her.  The interesting part as Joel goes in and saves her and takes her away from the operating table and laboratory.  To some Joel is seen as the hero as he saves his adopted daughter from death and takes her to a settlement to live in a somewhat peaceful area.  Though it can be seen as an anti-hero who is selfish and only wants him to be happy because he lies to Ellie that the scientists are not searching for the cure anymore.  In the end one has to decide on what is heroic or not.
