(Chew, Image Comics)

Chew is a phenomenal comic book, with an honest and perfect ending that is both darkly funny and depressingly tragic. But in the second to last issue, the whole book pays off.

In the story, aliens came to earth and threatened the world with destruction as long as there was anyone on earth who had eaten chicken. Tony's wife sacrificed herself to create the solution: a manuscript whose effect was to kill every person on Earth with chicken in his or her system.

Tony refused to use it, knowing that it would kill millions of people. But his partner, John, knew that failing to use it would result in everyone on Earth dying. He pressured Tony into doing it, and when he did, John dropped to the ground. He’d eaten chicken for lunch that day. John knew full well that he was signing his own death warrant, but he still did what he thought was right to save everyone he could.

A selfish character's last unselfish move.
