Obviously RP answers, as all the non RP answers are going to be the same as 'Brigante’s
Nabaal does not really hate as such, however he does have ‘Views’ of varying severity.
He has nothing against Goblins, personally, he finds them greedy, and of vastly questionable morality, being a charitable soul perhaps their greed is because they lost everything when Kezan was destroyed, and need to make it up…Or perhaps they are just greedy little swines…
He has absolutely nothing against Tauren, and it pains him that they have to be enemies. Whilst he is devout in his faith in The Light, he can understand how a ‘primitive’ society, observing the sun and moons, may have attributed them to an ‘Earth Mother’ figure. With the recent knowledge that Azeroth is indeed a ‘She’, and a nascent Titan to boot, Nabaal has started to wonder if the Tauren were actually on to something, when they revered the ‘Earth Mother’
He is torn on Blood Elves. He saw the hideous excesses of the Sunfury in Outlands, He saw the Sunhawks (Not Brigante’s guild, honestly! We’re not that kind of Sun Hawk) and how they collaborated with Legion forces, He learned that they were the ones who had sabotaged the Exodar, killing many Draenei as it crashed to Azeroth. He had almost lost his Light then, heading to Shattrath, there to go forth with like minded Draenei and smash every blood elf skull he could find.
Then came Voren’thal the Seer, with his army of Blood Elves, later to be known as the Scryers. A’dal, the Naaru accepted them…and who was Nabaal to go against a Naaru’s judgment. He tried to understand the horrible wound that had led the Blood Elves to what they did, and once the Shattered Sun were formed, he volunteered. He fought alongside Blood ELves and learned that they are not -all- bad. Just some of them.
Trolls are harder to pin down. He understands the Darkspear are intelligent, and the Zandalari also, but he honestly sees the rest of the Troll tribes as little more than savage creatures of animal intellect that will attack without reason. If you are attacked by a wild animal, with no other recourse then…You Kill it.
Orcs can die under his righteous ire and the fury of one on Draenor when the atrocities started and it became Outlands. Rare is the Orc that he would spare. From his ‘View’ King Anasterian and King Greymane had the right idea. They should have put the Orcs to death, in as humane a fashion as could be. There would be, no Horde, and the world not riven by its wars.
Forsaken should be given mercy. That mercy is death. They should be allowed to -let- go. What was done to them was terrible, but then making that cycle of horror continue by expansionist invasions and slaughtering the living cannot be excused by the initial atrocity committed against the Forsaken. He grants them mercy, with his hammer, or sword, and the Light.
Once the Forsaken are all gone, he will assist the wayward souls on his own Faction, and assist those not able to let go, to let go, the Death Knights that is. And he will do it with Mercy and Love.
Huojin? He likes the fact they are jolly folk, and does not understand how they could have been inveigled into working with such a grim bunch as the Horde…
