((Partially related note: We need more blog pictures, there's no Uncle Owen for episode II, III OR IV))

Well it's a simple question, but there's not much background to go with it that I know of! It's been a question coming up a lot due to Owen looking anything but hateful at the end of Episode III.
That being said any imput from people who have read the "Last of the Jedi" youth series would be helpful since that could hold some "official" answer.
__________________________________________
So here's what we do know.

Owen knew Anakin was a Jedi.
He knew that Luke was Anakin's son.
He (almost surely) knew Obi-Wan was Anakin's master.
He knew Anakin was his step-mother's (Shmi's) son.
His father married Shmi.

What we don't know for sure.

Did Owen know Anakin was still alive and had turned into Darth Vader?
Did he know how Anakin had "died"? (At the hands of Obi-Wan)
How did he believe/know Padme had died?

So I now present to you my theory on why Owen seemingly hated ol' Ben Kenobi.

"You killed my mother!" -
Assumption: Owen doesn't know that Anakin is alive, he simply knows he died while on the path of the Jedi (Order 66 or otherwise). What reasoning would Obi-Wan have to tell him otherwise? If Vader had decended on the Lars family Luke was as good as dead anyway.

That's somewhat besides the point though. The primary focus of my point of view stands as thus: Owen knew Obi-Wan was Anakin's Jedi master. He knew his father loved Shmi, he knew she loved Anakin, Shmi talked about Anakin all the time (From the Episode II novel) so he knew Anakin had left her to be a Jedi and Shmi was heartbroken.

Making those connections Owen felt that Obi-Wan and the Jedi were a direct cause of Shmi being heartbroken: A cause for hate in itself.
In a wider sense though he blamed the Jedi for taking Anakin away who could have saved Shmi (people are rarely rational when relating to family deaths, so Owen likely ignored the fact that it was the Jedi training that would have likely given Anakin the strength to save his mother). If Anakin had not been taken away from Tatooine then he could have saved Shmi or at least perhaps easied the grief of...
Cliegg Lars, Owen's father, widely accepted to have died from grief at the loss of Shmi.
Owen believed that, albiet indirectly, Obi-Wan and the Jedi had killed his father and his mother by taking Anakin away from Tatooine.
Thus Obi-Wan's comment:
____________________________________
Luke: No, my father didn't fight in the wars.
He was a navigator on a spice freighter.

Ben: That's what your uncle told you.
He didn't hold with your father's ideals.
Thought he should have stayed here and not gotten involved.
____________________________________________________
Owen would have done anything to keep Luke from following ol' Obi-Wan on some damn fool idealistic crusade like Anakin did. Going down the same path that brought Owen so much pain. Owen wanted to hold onto the last bit of Shmi he could. Luke.

This is what I think is the best, most likely cause, but perhaps I'll write something up on other ways Owen's character could develop based on other feelings he may have had based on what he knew.
What do you think? Is this point of view of Owen likely? Or something far different?
Keep this in mind though: Aunt Beru certainly didn't harbor the same feelings. This could of course be simply due to only Owen knowing the truth of Anakin's fall for one reason or another. However if you look at it from this point of view, she wouldn't have had the same feelings because Shmi and Cliegg weren't her parents.
