[Star Wars] How could Obi-Wan Kenobi be turned to the dark side?

Guy seems pretty much incorruptible, but I don't know that I've ever seen anyone make a sustained, targeted effort to get him to turn. What would be the best approach to take to recruit him to team dark side?

Give him something that he couldn't protect, make him choose between protecting one person over a thousand, and do it over and over. Obi-Wan has always been a man who valued protecting others and aiming for the best solution, but force him into enough trolley paradoxes and the man will break.
