[Warhammer 40K] which chaos God would despise orks the most?

I'm asking this as I wish to have create a chaos army to rival against my ork army (Goffs) so I can play games with my friends/brother/ father etc.

From what I've read. Orks are asexual and have no desire for any of the indulgences that slaanesh offers his/her followers.

They do not wish for immortality so they bare no interest in following Nurgle.

And they have no interest in Tzeentch as they simply have no interest in making long term plans.

From what I understand however, khorne seems to at least tolerate the greenskins as he feeds off of their bloodlust.

All of this being said, which chaos God would most likely go out of their way to oppose and wage war on the orks? I personally feel it would be Tzeentch as I reckon that a species with no ultimate goal in life besides fighting would anger the changer of ways.
Any comments are more than appreciated :)

I think you're right about Tzeench being the closest to an antithesis to the Orks. They spread like disease, revel in combat, and find joy in the suffering of others, so Nurgle, Khorne, and Slaanesh probably see them as, at the very least, entertaining. Tzeench, on the other hand, would see them as brutish, unsophisticated, unintelligent wild-cards that have a much better chance of getting in the way of things than they do actually helping. They're also incredibly difficult to change, in that, they have a very specific way of doing things that really doesn't evolve over time. 

Tzeench has nothing that he can exploit within the Ork society, and they have every chance to fuck things up for him, so, at the very least, he's gotta find them incredibly annoying.
