That's impossible--you would never be able to willingly turn away from the Dark Side after becoming a full-blown Sith. The lure of the Dark Side is such that even the most powerful Jedi find it difficult to resist.
the only reason darth died was because he threw the emperor in the tunnel as he was electicuting luke which made darth take the blow, that made darths health diminish then eventually he died, it wasnt about him turning to light again. Its kinda like in KotOR, you can start to go down the path of bad, but then with enough energy and time, you can eventually turn to light again.
KOTOR gets a lot of things wrong. Its judgment on love betrays it not having paid attention to AOTC. It tries to make out that the Jedi are wrong to say love is wrong because they think that the only associated problem is passion. But it is not- the problem is attachment. No matter how noble the love, it creates attachment, and if you have attachment you fear to lose it- and we know where fear leads... GL actually directly states that it is Anakin's attachment to Padme that gets him, and I think we can all be satisifed that Anakin's love was as pure and noble as it gets. But still fatal. It is just the way it is for a Jedi and a game based in the SW universe should remember that.
(noting, of course, that Anakin also states that in GENERAL, Jedi are encouraged to love. It is the focussed love/attachment to one person that is forbidden and with good reason)
Vader's death was an inevitiable consequence and price for his redemption. You have to look at these things as a wider plot arc- the sacrifice was his price. The films are VERY clear on the one way nature of the Dark Side. Once you give in, you are finished.
If you think there was a scenario where Vader could have just turned back to Anakin and lived happily ever after- absolutely not, and this would go against what GL wanted to show.
where in KOTOR did it say that passion was bad and not attachment? i think that their point was that passion is a dangerous path to go down BECAUSE it leads to attachment. If you are passive about something, obviousely you're going to end up attached to it...its inevitable. I think that they told the jedi to just avoid passion for anything because you'll always end up attached to it. but whose to decifer love and passion?
Jolee said it was passion that was dangerous, not love, in an extended sequence designed to portray that. You are also encouraged to have a romance with Bastilla, if male.
The film is very clear- love like that is DANGEROUS and is forbidden with good reason. And yes, this treads all over the EU, but there you go.
