The point is not just that he's blinded by the flag: He's boldly marching into the void, confident. "wrapped in the flag" is a great saying.

into the void, or off the edge?
"off the edge" is a clear interpretation of the statue. "into the void" is a bit more of a stretch. IMHO.
But that's art for you. Everyone has their own take on it.
Worse than a void because a void is not necessarily bad. Walking “off a cliff” rarely ends well.
