You're right. It's not the matter of having darkness inside as much as not acting on it. It's about choice, and in this episode Xander doesn't have it. But it was Xander's choice to lie to Buffy in Becoming, his choice to summon Sweet, his choice to grab and axe and try to kill Spike. That's Xander being weak, giving in to the darkness instead of fighting it.
