I still can't fathom the selfless Knight Obi wan letting the person he loves most in the world burn to death even as he profeses his love to him
If he can show such empathy to Maul, the person who murdered BOTH his beloved mentor and the love of his life, I still think he would have given Anakin a mercy killing.
The only thing that contests me so much is the fact, Luke, the guy who REFUSED to give up on Darth Vader when everyone else had, was briefly tempted to murder his nephew just because he was being tempted by some bald alien across the galaxy. Other then that, I like how he seemingly acts like Kreia.
