In my world, heroes don't run from sexual assault trials.
Is he afraid of prison, or of the sexual assault prosecution being a sham to punish him for what he published? Chelsea Manning was prosecuted and sentenced and more-or-less tortured for the actual things she leaked. She's a hero - she did the right thing for the country even though she knew what it would cost her. She didn't run. She was sitting in solitary confinement while Assange was tweeting in an embassy and claiming political asylum.
Someone who wants to change the world, who seeks prestige and power, and who gains fame from someone else's sacrifice can be many things (and perhaps many good things) - but I wouldn't call him a hero.
