Possible allegory for Jesus Christ?
I know this sounds silly, but forget RoboCop...could THIS be a possible allegory?
For a start, our hero has a beard, he is very decent and honest (not supporting Cragie and protecting that girl) and is determined to fight evil.
Also, when he makes his entrance into the building at the end, light shines in as if signalling a resurrection and note how Chuck's arms are laid out as he's being beaten up in the bar (like a crucifixion), as well as the blood around his head.
