Nai Fohl, I am afraid you still have it wrong.
First of all, Obi-Wan's line about absolutes does not override what GL himself has said about good and evil. It was clearly a riposte to what Anakin had just said. You could apply it to someone's interpretation over whether something is absolutely right or wrong, but the fact that good and evil as absolute entities exist in Star Wars is, I am afraid, an independant fact- it was the reason he made the Saga and goes to the core of Star War' existence.
"Why do you think Luke stoped the attack on his father in ROTJ a second before killing him ? "
Because he saw he was turning INTO Vader. Nothing to do with love. Surprised you could think otherwise.
"Do you really think that it was "reflecting on his life" enabled Vader to kill the Emperor ?"
Yes. Why? GL said so. End of argument- sorry.
"See...THAT is the point. If you can not CONTROL your emotions and let go of the attachment you are doomed but that again is your personal decission and it's not necessesarily true that an attachment automatically leads to the dark side. Anakin for example is not attached to Padme...he is obsessed with her - so much that he can't accept the fact that she has to die like everyone has to die. He can't let go of the attachment. If somebody can...if he can accept the fact that people have to die and won't let his emotions overwhelm him than an attachment isn't automatically leading to the dark side. "
I am afriad both the films and GL contradict you. Again, GL has directly said that Anakin's PROBLEM is that he forms attachment. Attachment for a Jedi is bad- again, from GL, and so irrefutable.
If you let go of the attachment, that is not having the attachment. As should be obvious. So, attachment, bad- getting rid of attachment = the solution.
"At the point where the attachment comes into the game it doesn't have an effect on a "Jedi". Bastila isn't a Jedi at this time since she has already joined the Dark Side. Same goes for Vader. Their attachments allowed them to be redeemed from the Dark Side"
That is sheer pedanticism. Very well, if you prefer- attachment is bad for a force user. It will send you to the Dark Side, and it will only strengthen that position if you have them whilst Dark, because attachment causes fear.
So sorry, but you are continually wrong here.
