It does matter why. Same reason it matters why Dany became the way she was. They weren't that different in the long run. And no he didn't keep her alive to sell her to Dothraki. He never intended to sell her to Dothraki. He literally raised her from the time she was an infant to her early teens on his own, with the intention that they would someday get their home back.
Again your taking a very simplistic approach to a more complicated story that is precisely designed to be more complicatd
He sold her to the Dothraki. He was an abusive creep leading up to selling her off. He just got pissed because he couldn't be a creepy bastard anymore and Drogo didn't care about listening to him.
He wanted power for himself. She was an object to be used as currency for himself.
The point is, she didn't owe him anything.
It is irrelevant but I answered it anyways even if you want to pretend that I didn't. Once Drogo was dead, why didn't Dany just sell her Dragons to Illyrio or someone else with a shit ton of money and just buy a House in Braavos or something? There's no reason why that wasn't an option. I'll give you that she was stuck with the Dothraki, but once Drogo died, she very easily could have left with Jorah, that was another option for as well. She also very easily could have interceded in Viserys death. She had choices along the way. It was never all or nothing
Oh, I've always figured Jorah was essentially her conscience. Without him around, I knew her character was destined for a tragic end.
I'm just disappointed the writing wasn't more nuanced. Everything that happened tonight was clearly telegraphed ages in advance. Of course Varys would be wrongfully executed. Of course Jaime was going to fight and kill Euron to become a Kingslayer twice over. Of course the Hound and the Mountain were going to die fighting each other. Of course the Golden Company would prove as useless as the Tyrell army. Of course Arya's plot armor would be strong enough to repel falling debris, dragonflame (now with concussive force!), and a stampede of a million people losing their goddamn minds. Of course Jon Snow remains Emo Snow. This was visually interesting, and I prefer it to the Battle for Winterfell two episodes ago, but it's still standard storytelling fare for this season.
