In BG 1 and 2 I didn't have to make a companion choice based on my good/evil playstyle. Why should I have less freedom in 3?
That depends if you want them to stay a companion or not, I'm pretty sure Korgan is eventually going to fight you if you're too much of a goody two shoes and he's not the only one who'll either walk out or come to blows if things get too far stretched from their alignment.
