I don't think so, at least not in a meaningful way.
Morality is highly subjective, to begin with, as is intent...
And I'd argue that personal and public/state morality are separate, at least to an extent.
I'd argue that personal morality is based on intent (ie, if I mean to be kind in offering you a peanut butter and jelly sandwich not knowing that you're highly allergic, I'm at fault in a practical sense--and possibly you as well for not telling me or checking what you're eating before you chow down--but I'm not at fault in a moral sense, I didn't INTEND to cause you harm and in fact intended to help you, and there's no way I could have known that my action would cause you harm as I didn't know you were allergic.)
By contrast, the morality of a state is the sum total of the actions of its people...
Intent matters here, but since nearly every one of our 300 million US citizens have different intentions when they pay taxes or even when they vote for political candidates (20 Obama voters could have 20 different reasons for voting for him, ranging from a hatred of Romney and the opposition to true endorsement of Obama to a blanket endorsement of the Democrats to self-interest insofar as Obama might be friendlier towards certain social positions--ie, gay rights/marriage--than Romney, so if you're gay, and your choices are someone who's at the very least ambivalent and at best someone who's grown to endorse gay marriage on the one hand and a candidate whose Mormon beliefs--and in this case I feel it's fair to reference them, belief is private, but given how high-profile the Mormon stance on gay marriage is, I think that's a fair point --well...if gay marriage is a central issue for you, then you COULD vote for Obama just the same as a guy who might hate gays but endorse Obama's other policies) I think individual intent is muddled to the point where in most cases it becomes a non-factor in terms of counting individually--
Hence why it coalesces and counts in "group intents/morality."
This can be unifying (Latinos, female rights activists, Jews, blacks, and gays can conceivably all come from very different backgrounds, but broadly-shared collective intent has helped the Democratic party to build a powerhouse political base come election time) and it can be destructive (the intent of the Religious Right, Big Business and Libertarian sects of the Republican Party right now are all very much at odds, and that arguably caused them to lose the election as much as the New Democratic Coalition described above helped Obama win)...
That neither validates nor refutes the position, you can unify a bad platform or destroy a good one...
But it does mean that individual intent is given over to the whole.
As such, we all have different intents when we pay taxes.
Further, we have very little control over where that money goes.
You can be shoveling coal into the boiler to make a steam engine go, but you have no control over whether or not the captain suddenly decides to break out some hidden guns and raid another ship or kill his passengers for their money.
You could argue the ship would never be in position to fire on the other ship if the coal workers didn't power it, but as they didn't know what their raw efforts were going towards, individually they're not at fault, while collectively they are.
As such, you can't blame a small, nice, happy, tolerant German family for WWII...
That being said, they're collectively implicated when we blame "Germany" for certain actions in WWII.
