20 Essential Comic Issues You Must Read Before You Die
13. Daredevil #191
Frank Miller's run on Daredevil is legendary for the way it transformed the character from "Spiderman-Lite" into the dark and brooding vigilante we're familiar with now.
A lot of the series dealt with questions of morality and law, questions which came to a head in his final story Roulette.
After paralysing Bullseye as revenge for the death of Elektra, Daredevil visits him in hospital. He pulls out a revolver and begins playing a game of Russian roulette with the villain, all the while debating his stance on not-killing his villains.
It's a stunning character piece which ends on the perfect twist, Daredevil's gun was empty all along.
