I was just questioning if a primary or significant response to a story seems to be to question where it fits into continuity, and the point of the story wasn't about introducing a continuity twist but to get to some other places, is that really a good story?
I'm not sure I can untangle that, beyond saying that the original example -- not having Superman refer back to an earlier story -- would be unlikely to make people confused about where it fits in continuity, any more than him not mentioning his college days makes people think the story might be set before them, and that since the general reaction to the Thunderbolts storyline we're discussing was that it was quite a good story, then sure, why not? [Heck, for that matter, nobody seemed confused about where the T-Bolts story fit into continuity either.]
Adding "not intentionally" or "unless there's other choice" might work, too.
I don't think so. It might make the line more descriptive of actual history, but it makes it both less powerful and out of character -- Hawkeye's not delivering a historical dissertation that accounts for every possible example, he's yelling at someone. It's just not necessary, in that context, for him to be that specific; he's making a general statement.
Or maybe you could delve into how he felt when Mockingbird killed or something.
Why would he? That he feels bad about her death has nothing to do with whether heroes should or shouldn't kill -- she was killed by Mephisto. So if he did that, he wouldn't be mentioning any earlier killings by Avengers (the original point) or bringing up an example that alters or even expands on his point.
It'd just be a continuity mention for the sake of continuity mentions. He could also mention how he felt when his brother died, or his parents, but it doesn't actually add anything to his point, since none of them were killed by people acting as (or trying to act as) heroes.
By contrast, Superman having a conversation of "I was a killer" just sounds wrong - not just turgid - on so many levels.
Well, keep in mind that my original comment was that I wouldn't refer back to the earlier story, so no worries there.
