Yet he's had so many opportunities to kill Bullseye and hasn't done it; he has more reason to kill him than anyone else.
He has come close - in the aftermath of Bullseye killing Elektra, DD dropped him from a height of several stories, which led to his longtime hospitalization and adamantium bone replacements (actually, DD was holding him up, and Bullseye was going to stab him anyway with a sai, so it could be justifiable self preservation.)
Then while stuck in the hospital, DD appeared at his bedside and played Russian Roulette with a .38 on him, only to reveal as he pulled the trigger on the final chamber that he had no bullets. He said they were just stuck together.
Still looks kind of deliberate to me considering what DD says, despite Bullseye trying to stab him.
