Correct me if I'm wrong, but I'm pretty sure Godzilla was an anti-hero in the new film. He didn't actively try to destroy the city. Though, the lack of military response towards HIM may have contributed to this. Given that, his attitude towards Japan solely depends on whether they attacked him (mostly via the hydrogen bomb), threatened (either by military or another kaiju), or panicking like he did in Godzilla v.s. Destroyah.
The title of the piece is not prescribing "roles" to the two versions of Godzilla per say pictured here, it's merely a descriptor of what roles he has played in the past, but technically they still apply even to the new Godzilla....he's a giant beast, he inevitably causes destruction, and people fear him, but to my surprise he ended up being a defender in this new movie as well. There's no need to nitpick, it's merely a poetic title.
No it's fine, it just surprises me how often my artistic intentions kind of get lost in fan dissection My original "The New Guy" picture unintentionally started a flame war between Zilla haters and non-Zilla haters, that was all kinds of not fun.
