We're not supposed to think that dialogue is "kewl" though, or whatever - the only one who spouted stuff like that in the story is the main villain - Dr DOOM. The intention is to show that Doom is - an utter jerk.
Which he is. The biggest misunderstanding of Dr Doom that a writer could make is that they insist on Dr Doom being noble - because he isn't. Noble compared to whom? Spider-man? Captain America? Reed Richards?
H*ll no! Compared to the likes of Carnage? Probably. But that doesn't actually make Doom noble.
He's not. Bendis take was a bit different, as it was pretty much Doom having one of the worst days of his life, up to that point - I believe what Bendis was going for here was to show a somewhat more flawed Doom, who is actually under pressure - who can't quite keep up his usual superior bravado in the face of the situation. It's different, but not entirely unreasonable.
The story of course ends with Doom humbled - defeated, dethroned, and his armour ripped apart by Sentry - revealing his face to the Avengers.
Hmm, maybe. Why DOESN'T Batman have this problem though?
Yes, they do. They've both talked about it in the Wordballoon podcast - basically, Bendis has known Hickman for his entire career.
It was actually a thing at Marvel there for a while - I recall that another example is Ed Brubaker and Matt Fraction - Brubaker got Fraction his first big gig in mainstream comics - writing Immortal Iron Fist with him.
