What's right and wrong depends on how you view the story, Zarro. For everyone who says how they felt was right, I find myself shaking my head, anyway. It always seems like what's right for me is a bit off balance, hehe.
My own "right" choices:
Warden was a Cousland rogue, who ended up marrying Alistair in the end.
Everyone was recruited, including Shale, Leliana and Sten.
Anvil was destroyed and Bhelan rules the dwarves.
Brokered peace between the elves and the werewolves.
Saved Connor and even Isolde, Connor is not possessed.
Disappointed Cullen and saved the mages.
Gave Sten his sword and found Goldanna (although would've rather beat her down).
Alistair executed Loghain.
Executed Sophia and left Avernus alive, although ethical. Never chugged the potion.
Saved Amalia from Kitty's possession.
Didn't defile Andraste's ashes.
Gave Morrigan a grimoire and tried killing Flemith.
Asked Alistair to complete the Dark Ritual.
Made killing blow against the Archdemon.
Saved the city of Amaranthine.
Killed the Architect.
My Hawke, on the other hand, was an aggressive Garrett.
Hawke was a mage but generally leaned towards Templar control of magic in all dialogue and options.
Was a mercenary during the prologue.
Romanced Fenris. As many times as possible, sigh.
Turned mages over to the Templars during Act 1.
Asked that Keran stay in the Templar Order, and let Keran go during Act 3 conspiracy.
Carver stayed in Kirkwall and joined the Templar Order.
Didn't side with Petrice and enjoyed watching her die.
Isabella came back with the Tome and saved her from the Qunari.
Earned the respect of the Arishok and fought him in single combat.
Bartrand was killed and Varric was saved from taking the shard.
Killed the Bonepit dragon.
Sided with Larius and received Malcolm's will.
Let Tallis keep the Qunari scroll thing.
Helped Aveline romance and marry Donnic (awesome cute quest).
Was friends with Cullen.
Was friends with Sebastian, too, but that's not in the Keep options, hehe.
Merril's clan still alive and she destroyed the mirror.
Knifed Anders ("Anders, what have you done?!")
Sided with the Templars.
