Turning to dark side: Could have been handled better
I guess this should include a spoiler warning for those who haven't played JK yet.
Ok, you kill cvilians and droids and you end up turning to the dark side. That part I get, but the one thing that never made sense to me was why Kyle would kill Jan. Turning to the dark side doesn't make one go beserk and slaughter everyone around them without provocation, it makes them give in to hate. Kyle has no reason to hate Jan. Yes, he might eventually become evil enough that he would lose his temper and kill her, but at that point in the story, she's still his loyal friend.
I suppose it was included for shock value and to show how evil he's become but to me it just came off as being cheap.
