2. in the deep roads, unless you allready know what is going to happen, you can`t really know if Carver will become a warden if Anders is there with them. Thats metagaming.
And... what's your point?
The first time I played DA2, I took Bethany with me into the Deep Roads and not Anders.
She died as a result of my decision.On a seperate play-through, I left Carver behind.
He ended up joining the Templars as a result of my decision.I honestly have no idea why you mentioned metagaming, tbh... it seems completely off topic, considering you don't HAVE to know every possible result for every decision for it to be, you know, a choice.

3. Conner is possessed BEFORE he meets the Warden. He can`t do anything about that. Same goes for the Wynne example. That actually happened before the Warden was BORN. However the BethanyCarver being infected in the deep roads happens on his watch. And there is nothing at all he can do about it.
Once again, I don't see your point. You can choose to make Redcliffe your very first stop outside of Ostagar, and Connor will still be possessed as if Jowan hadn't just escaped like, a week ago. =/
There is no work around to avoid this scenario just like there is no work around for Carver/Bethany in the Deep Roads with an Absent Anders. No matter how fast you get there, DAO demands that Conner be possessed before you get there the same way DA2 demands that Carver/Bethany have a failing immune system that forces them to contract the Blight. Where/when they get possessed/sick in relation to the PC
doesn't matter. What matters is that you can't stop Jowan from acting on behalf of Loghain (or Howe), and you can't stop Carver?Bethany from contracting the Blight.
Both games have restrictions that the player has to abide by in order to push the story forward.
And Wynne's possession doesn't happen before the Warden is born. It happens when she attempts to protect one of the other mages from a demon. She defeats the demon, but the fight leaves her on the verge of death. A spirit of Faith (as Wynne likes to call it) that had been watching her from the Fade since childhood possesses her to save her life.

4. And if the girl actually gets raped, will this have a negative impact on the story at all? Or influence the ending in some way?
Is this a serious question? Because I struggle to think of a single scenario where rape ever had a positive impact on a story. .__.
Once again: no matter what decisions you make in DAO, the end result is always the same outcome: you defeat the Archdemon and the Blight ends. You seriously seem to be arguing that this was perfectly okay for Origins, but unforgivable in DA2.
Although if I may go out on a limb, I think your actual problem with DA2 is that there were no epilogue cards... The decisions you made in DAO did not influence the end game battle any more than 'templars or mages' did in DA2.
However, the consequences of your decisions throughout DAO were confirmed in the epilogue cards (which were/are still subject to change) whereas your consequences in DA2 were either
shown throughout the acts, or are being saved for DA3.

5. Nobody knows who wiped out her clan. Except Merrill herself, and she helped slaughter her own people. I doubt there will be consequences when the only witness was her.
The Seekers know... as well as anyone whose heard a more truthful variation of Hawke's story... and presumably anyone who was still with Hawke by that point (like Varric.) It's also possible that Merrill chose to tell others upon leaving Hawke (as all of the main cast do, save for the love interest.)
