How can we trust someone that own dad wanted to kill everyone. so why should we trust him.
Because he has legendaries.
You don't have to trust him, I don't, but so far he's not working against us so I'm good.
"Reminds me of a dog, you stare at it while it's playing outside... Running around in a circle, then stopping up, wagging with a wide "grin". Jumping around until you call for the dog, then it lowers its tail because it think it's done something bad... And then you throw the ball, seeing the tail go straight into the air in bliss! ^^" - Gehco

I see the relationship with Wrathion as more of a "common enemies" relationship.
It wouldn't be smart to trust him.
I blindly follow anyone willing to give me those gems.
Because he isn't corrupted like Deathwing was?
Edit: Nvm, I'm confused.
In reality the relationship between Wrathion and Us atm is very one sided. He's giving us powerful stuff (Gems) and eventually equipment and we are giving him? Nothing. Simply killing a Sha that needs to be killed regardless and gaining favour with him by helping out the Pandaren and our own Factions.
I think he's trustworthy as the situation stands now, but it might be a 'You either die a Hero or live long enough to see yourself become the Villain' type dilemma. Either he's going to do lots of good and die in a glorious and heroic way. Or he'll get corrupted or his plan for Azeroth won't match up with what the Horde/Alliance want and he'll become a Villain.
He was from the pure black dragon egg Rhea gave her life to protect, right?
Remember that the Black Dragons weren't always evil.
Hey, remember when I dropped my keys and you thought the phone was ringing?
I'll trust him for as long as his requests are reasonable and in line with my own plans. The moment he starts going past those boundaries, well that's when we start seeing how well Wrathion responds to the words "no". I'll reserve judgement on him till I see what he does when he doesn't get what he wants with charm and gifts. Will he stay diplomatic, or will he go further where he left of when he went after his dad & the rest of the old flight by assissinating and such.
