She was a means to an end - Targaryens marry their sisters to take the throne, so he needed his sister in order to restore Targaryen rule. She became a symbol and an object that he treated like dirt.
2. He didn't just knock her around a bit. He physically, emotionally and sexually abused her and then sold her to be wedded and raped by Khal Drogo. From Dany's point of view, even if he had been the 'loving brother' you portray, this is the ultimate in betrayals. He promised her she would rule by his side, and then traded her like a goat to a barbarian. Oh yeah, and the night before she gets married, he tries to rape her.
3. Despite having wise advisors, Viserys ignored them because he was a petulant child. He was told that the Dothraki don't buy and sell but receive and offer gifts, so he needed to be patient. But he was so arrogant and angry over the 'indignities' he felt he was suffering. He kept demanding his army *now* or else...what?
4. He then became ridiculously jealous of Dany for being in a position over him, so much so that he grabs her by the throat and calls her a slut. When he's punished for his assault on her, it only makes him more angry. He tries to steal the dragon eggs for his own ends and when that sister he supposedly cares for so much tries to be nice to him and offer him clothing fit for a Khal, he hits her again.
5. Here's the kicker you left out - he drew his sword in a holy place, and in front of Drogo, he threatened to kill Dany *and* their unborn child to get what he wanted because he sold his sister and wanted payment. He held his nephew and sister hostage in front of Khal Drogo to get what he demanded despite being told to wait for it.
So Dany, who had been beaten, abused, sold and degraded by her brother is oddly not upset that, right after he put a sword to her belly and threatened to cut out her unborn child because they were in a place where the Dothraki can't draw blood but *he* can? No, I don't blame her at all. She repeatedly reached out to him, and he assaulted and tried to rob and rape her, so yes, he may have started out years and years ago as a caring brother, but that went away a long time ago. In the books Dany was what, 13? So all she's really known is what her brother told her - that he saved her life, they were going to marry and take back what was rightfully his (not theirs). At no point does he ever show any love for his sister, only that he values her as a prop and then, later, as property. He believed he owned her and, in the end, he got what he deserved and I see no reason why Dany should have been at all sympathetic after all he had done to her.
