Great post Illustro Cado (and cool site too, your writing is high quality!), thank you.
I do have some remarks about your reply, though.
You state that intentions determine if you are a light or darkworker, and so the subject itself has the final say. Yet you also state that Hitler was a lightworker. But we cannot know this, if he was the one deciding. He could say he was trying to help his people, or whoever he said he was helping, all the while knowing he was just gratifying his own desire for power. In that case he just saw an oppertunity to gain power by a certain rethoric, and did so.
So to say that Hitler is a lightworker, would state that there is some sort of objective way of determining if someone is lightworker or darkworker. But intentions cannot be known (even your own might be hard to determine, on the most basic level).
Now I see your point about intention to service, that being the objective way of measurement. But again to know for sure is almost impossible. What is the underlying motivation for service to others? And could these change in the process, like you said? You could start out wanting to help others, and then get addicted to their dependency on you.
Perhaps you could differentiate between where someone is coming from, fear or love. Is he driven by fear (limit, not enoughness, etc.) and thus is out for himself or is he driven by love (abundance, acceptance) and trying to heal the whole. And perhaps this cannot be explained, only experienced.
But to me it's just a lot of talk about nothing. There is no point in being one thing or the other. There is no reward, prize or whatever. What there is, is results. And to get them, aligning with your goal, is the way to go. And to integrate different ways that work into something that works even better, well that's just awesome. But polarizing? Just limiting yourself to a certain set of actions, that fit the label, to me just seems unnecessary and sillly.
The mental stuff around it is fun to play with, but in the end, useless. Hitler was, just like everyone, a very complex being. One day he might think one thing, the next day something else. As far as his thoughts were in alignment, his focus was sharp and his results probably better than if they weren't.
He wasn't light, he wasn't dark, he just was (or was he?). Sometimes he was afraid, sometimes he was not. Sometimes he felt on top of the world, other days he despised himself. Now I've not known him personally, I just know myself and I think that every human being is like this. Being. Changing.
And in the end, we all have to accept who we are, what we do and where it stands in the world. In the end, we all have to try to convince ourselves we are lightworkers, of some sort. But we know so very little. And our primal parts (body, lizard brain) are so scared to die, and it's hard to tell where they begin and where they end.
Ok, I'm just babbling now... point is: manifesting what you want is what you... well, want. But there is no score being kept. Just try to manifest what you want. And if you find a way to better manifest, go for it. But don't label it or drag some spiritual stuff into it.
