Well by hard-boiled I meant weathered, cynical, world-weary type a la Bogart as Sam Spade in Maltese Falcon or more recently Bruce Willis in many roles including Die Hard. Blood-thirsty warrior is NOT the same as hard-boiled.
In the run-up to the Annihilation saga, I think Quill was indeed cynical and world-weary. At least thats where he was at that point in his "life".
Heres the wiki article for clarity:
Hope that clears things up.
edit: btw Ive read all the "modern" GotG stuff plus most of the recent (last 10 years) cosmic stuff. And ive read enough of the "classic" GotG to understand the characters. Frankly there really isnt much material compared to the other MCU properties and even within the comics Marvel has taken many liberties with the team. Because of this and because no one - not even many comic fans - has any clue who the GotG are is why I think that this movie will be by far the least faithful to the details of the source material. The movie could alienate every single GotG fanboy on the planet and it still wouldnt put a noticeable dent in the box office if the movie is good.
