Remember that Sven and his team desperately want you to try evil, and will reward you for doing so (your choice).
At the presentation I attended in Ghent, someone asked Swen what he considered the themes of the game to be. I didn't write this all down, so my memory might be unreliable, but iirc two things he picked out were trust and temptation, the latter of which is relevant here. And I think he said that the game would do its very best to tempt us into dark ways, but that whether we give in is up to us. Whether there will be a good payoff for turning our back on power, or whether virtue will need to be its own reward, I don't know. But I actually find this a really interesting approach, and for at least some of my character concepts am not at all sure where they'll end up, as I will need to play it by ear and see what feels right for them in the moment.
