I think I perceive Sargeras different to you guys,
The Titans, HUGE unthinking, unemotional, unforgiving beings that care nothing for life for it is too chaotic..
Sargeras, You can say what you like about him, but he understands emotion and his legion is very much alive and growing... his methods may leave a little to be desired but overall perhaps he is just trying to sustain uncontrollable, unpredictable emotional life in the galaxy?
out of the two I prefer Sargeras, I'd rather bend the knee to him than have everything wiped back to rock by the titans thank you very much.
He accepts our hatred because he's the hero Azeroth deserves, but not the one it needs right now. So, we'll hunt him, because he can take it. Because he's not our hero. He's a silent guardian. A watchful protector. A Dark Titan.
