In your opinion, which hero has the most charisma in the campaign?

Come on, he didn't help people out of the goodness of his heart. It was beneficial for him; I'm too lazy to explain why, but the idea that Markel helped people out of pure kindness... Never. But he's an excellent diplomat, as mentioned in his biography, and his diplomacy comes with a knack for it.
We're arguing about whether Markel always seeks his own benefit and doesn't help people out of kindness, which is natural for a necromancer, as I said. His image corresponds to the image of a necromancer, unlike Arantir, who is more like a knight without fear or reproach. You doubted that Markel helped people, and I gave an example. But he helped people, I repeat, from the point of view of his own benefit.
