Both of these guys are villains. Both of them treat everyone else as disposable tools in their quest for self-aggrandizement. The only difference is that Tony dresses it up in some noble language.
I think that this is another one of those cases where Japanese and Western concepts just don't match well. Neither of these idiots at all qualify as 'Heroes' by Western standards. They're more like 'Strongmen' or 'State Sponsored Thugs'. Yet the author here has them arguing their respective 'Hero' ideology.
...
This leads me off into an aside into wondering about various JP literature 'heroes'. ... But that would be a whole research paper. ... Yeah, I don't have the time for that.

Hero in Japanese. In short, the native Japanese words translate better as "Brave Man/Woman". But they also use 'Hiro' i.e. imported version of 'Hero'. It seems like the native concept essentially means 'Brave, Strong' but does not include the virtue that is inherent to the English concept.
In modern English, a 'hero' inherently is someone who sacrifices or risks their lives for the benefit of others. Unless, it's something like a 'Sports Hero', in which case it just means someone who is outstanding in that sport. And worth noting that 'Heroes' from older times are less virtuous, e.g. Hercules -- great strength, but a pretty mixed bag as far as virtue goes.
Hmm... The idea of a 'Hero' is one of the things that define a civilization, since it defines one of the major ideals for behavior of people in that civilization.
Well, that's the 'top of my head' rambling.
