Okay then, so briefly here's my train of thought with regards to Hank and why he's so angry at Scott.
I think a part of Hank has always looked to Scott as a moral compass.
It's not that Hank can't tell the difference between right and wrong.
But more like once he starts working on a problem he gets so single minded or obsessed with the problem that he can forget that right, wrong and common sense even exist.
It's how it turned himself in to a furry beast in the first place, it's why he almost went too far during Endangered species, it's why he brought the O5 to the present and it's why he's currently teamed up with the Illuminati in New Avengers.
He even has the Dark Beast to look at as an example of just how far off the moral path he could go if he doesn't keep himself in check.
So knowing these things about himself I think Hank might have held Scott up as the moral authority to aim for.
He held Cyclops up to a higher standard than he even holds himself and relied on Scott to often make those moral choices for him.
I've often found that Hank's been willing to make the guns, bombs and whatever other dangerous dohickeys need made.
But he also tends to avoid any situation were he may have "pull the trigger", often passing the tech he makes off to someone else to use or decide to use.
Usually he can rely on the person making those choices makes the right call. Be it Cyclops, Storm, Captain America or whoever else he defers to.
And in situations where a particularly hard choice had to be made he could at least feel that it was made with good intentions.
However more and more often Scott began to make more and more morally questionable choices.
Especially when he formed a hit team and started preempting threats instead of reacting to them.
So not only did Scott involve Hank he his morally questionable deeds, but he also took away Hank's support system.
If Scott can make all these choices then what's to stop Hank from doing them too.
Or worse what's to stop Hank from going even further than Scott and the only situation spiralling out of control.
So Hank decided to leave the X-Men and prevent himself from going to far.
But the problem is, even removed from Scott he still compromised himself.
He discovered that Logan was still running a hit squad but he was too invested in the new school to abandon them - compromised ethics.
He joined the Illumanti on a mission that could mean they have to destroy other worlds - massively compromised ethics.
When faced with death he took drastic measures to bring the O5 to the present and potential damage space and time - holy crap Hank ethics and even common sense out the window - WTF!
Even away from Scott he's doing all these things.
So I think he's more angry at himself and every questionable decision he's made and continues to make.
And that he's aiming all that anger at the man who he feels caused it all.
The man who he feels represents everything he doesn't want to become.
The man he had faith in to do the right thing and keep himself on the right road and who then broke that trust.
(And we now know what Hank thinks of faith and belief.)
Add to that the general turmoil of the X-Men's lives and the fact that Hank has watched many friends die (some for what he sees as Cyclops' cause).
Watched one of his closest friends (Jean) get betrayed by Scott and then lost her too.
Has witnessed or seen the aftermath of so many horrific events.
Has been tortured and left to fend for himself all so one of his best friends deemed him an acceptable casualty of war.
The guy is barely hanging on by a thread.
And where's all the anger that all those things caused going to get aimed.
How about the man Hank believed in , the man that took support system and beliefs and turned them on their head.
The man whose been heavily involved in some of the worst events of his life.
No wonder Hank is so pissed!
He's only human, and all that anger has to go somewhere.
