I forget which one it is but in one of the Matrix Revolutions trailers you see him in one of those mech gun suits, u know the ones which guard the gates of Zion? so i wouldnt imagine he'd last very long against 250,000 sentinals pouring through. But anyway i dont think his death is such a bad thing, i dont like him, and i dont think Niobe perticulary does (even though she is seeing him 😑 )
Ol' Deadbolt himself? They don't make him out to be a very sympathetic guy, do they? He is playing second fiddle to Morpheus (in both vision and, most probably, love life) and is routinely humiliated by the Council. His once chance to prove his strategic credentials are ruined by unforseeable circumstances.
Sigh... it's tough being a second-line character in a film!
