Part of Daredevil's appeal lies in the fact that his weaknesses and strengths go hand-in-hand. Matt Murdock is technically blind, but he also has the benefit of super radar senses. In other words, Daredevil has the ability to sense whether you're lying by the pace of your heartbeat, but he's absolute dogshit at Mario Kart.
The latter weakness is particularly inconvienent for writers when it comes to something like say, Daredevil making his costume for his origin story. You'd think this would make the writers reconsider their whole concept of the character and his abilities, but nope, Stan Lee just muttered through his demi-Hitler mustache: "The blind guy can feel color with his fingers."
It's one of those wacky throwaway scenes that you just accept because it was written in 1964 and people still smoked on airplanes. But then they brought it up again.
To recap, Daredevil knocked out a living Xbox Live username called "Shades McGraw," recognized that the two of them looked alike (presumably after groping his unconscious face), decided to disguise himself this man to get into a second location, proceeded to pet this man's head to get a "feel" for his hair color and then dyed his own hair to match his victim using pocket chemicals he keeps on his person for just this purpose.
Whew! That's almost as stupid as feeling colors through the heat on your gloves.
God dammit, Daredevil.
Cult favorite writer and barfight enthusiast Garth Ennis is known for taking the piss out of the world's most famous superheroes. Just about the only one Ennis really took seriously was the Punisher, and that's mostly because Frank Castle actually puts an end to his enemies.
In one of Ennis' best stories, the Punisher illustrates the difference between him and non-lethal capes. In this scene, Daredevil is trying to stop Punisher from assassinating a mobster, but Frank gets the upper-hand and knocks out his fellow vigilante. When DD wakes up, he's tied up, with a gun strapped to his his hand. The Punisher stays in the line of sight of the pistol; if Daredevil wants to prevent the killing, he's going to have to put Frank down permanently.
Matt Murdock's entire way of life was challenged, and he buckled under pressure. Daredevil pulls the trigger, trying to prevent a murder by attempting another murder.
"Trying" and "attempted" being the key words here.
Of course The Punisher isn't going to let himself get killed in his own comic, so he removed the firing pin from Daredevil's gun. The whole thing was a set-up to get Daredevil to face a no-win situation and come out a sheepish loser who questioned his own existence. And this was even before the Daredevil movie.
