If you care, too, there's quite a few times when Cullen will go for the 'moral' choice.
Seb takes over Kirkwall? Josie and Leianna will try and curry favor with him; Cullen's like 'Yeah, I know Aveline, let's kick the ******* out.'
Your herbalist hates someone and is incredibly vague about why they need to be out of the way? Cullen's like 'if you really think it's a threat, we'll get rid of their herbss, but we're not hurting them without an idea why' while Josie will have them imprisoned and Leianna will randomly kill them.
Some jerk noble is angry about all these elves and apostates around dying on his lands? Josie wants nothing to do with it, Leianna will harass them till they go away, and Cullen will have his people send aid to the refugees.
And, yeah, he can be the only choice to save your Dalish Clan depending on how you go around it, so my Dalish inquisitor is certainly in debt to him.
