Hell I still have the VHS Trilogy before the PT was even mention (Ep I). The first implementation made Han look like a dark character / "Go f#$% yourself" kind of guy. He took charge and knew how to deal with people like Greedo.
I never really saw him as a dark character before the change/awful CG job to Greedo firing and missing at point blank range. He did, after all, shoot in self defense. Someone was pointing a gun at him and had blatantly told Han he was going to kill him.
Then again, I grew up watching the Dollars trilogy and the Dirty Harry films.
