I mean, yeah, true. But it's not like you'd be doing it out of any particular love for Zariel or agreement with her. I think if a theoretical Tav is going that route to get Zariel off of Karlach's tail (and also I suppose bargain out a new upgraded heart for her, to justify the means) then it's clearly a Tav who's on Karlach's side and therefore likely despises Zariel for what was done to her. Therefore they're also gritting their teeth and bowing their head to a person they despise, likely signing themselves off to object misery for the duration of that contract. That loops back to this being a sacrifice and makes them less of an "asshole who is willing to work for ZARIEL" and more of a "dumbass who is too quick to screw up their own life without asking if I want them to do that for me".

I think that would make Tav sort of reminiscent of Wyll. A desire to save someone (the city, the lover) mixed in with sharp desperation of being helpless to - and met with an objectively questionable, but effective offer from an evil entity.

Granted, the city didn't exactly thank Wyll for his sacrifice either, but this would be a whole other sort of an informed situation on Karlach's part. Even if Tav was bound to never tell the truth and forced to pretend they've just switched sides, she'd have to figure stuff out when that switch'd miraculously come with her life being given back to her and such.
