Zant at end of TP *spoilers!*

Serves Ganondorf right for toying and using up Zant like that!

When Zant cracked his neck at the end, it made me gain a bit of respect for him.

I see it more like Zant pulling the magic of his tribe away from Ganondorf and when Ganondorf is left without the ToP and the powers of twili he has only his own magic and that is not enough to keep him alive considering the amount of his injuries. You see the ToP fading from him and it would make sense that since the goddesses pulled their power away Zant would after his death would see the error of his ways and try to correct his mistakes by helping as much as he can. I don't see anyhow Zant actually ether having the power or the need to Crack Ganondorfs neck considering that he already has the Mastersword jutting out of his abdomen.
