Bleh...just another reason why I don't like Damien. And maybe it's just out of context, but I hate how it makes Tim look so frigging spineless.
The reason why Batman, Robin, and Nightwing don't kill, isn't because they're afraid to take a life, but because they know what it could lead to. They don't kill, because the very act is a slippery slope, that lethal force will be an answer for every situation. And when will it stop? Who are they to decide who lives and dies? That's a level of power that no single man should have, because it can easily corrupt.
