i guess.
its not a splitting hairs kinda thing. i can't really specify what qualifications would officially register you as a hero or not.
in this specific case, if you're forcing my hand, i think i'd much more readily qualify this guy as "inspirational" before "heroic." not that a hero-argument couldn't be made, and not that i couldn't even be swayed by said argument, but... i think the former much more adequately describes what i've read, versus the latter.
