[Star Trek / Star Wars] Would a Vulcan make a good Jedi?
gpt
Yes, but they'd make *great* Sith.  Vulcans are a psychically-inclined species, which presumably make them more force sensitive.  Like Jedi, Vulcan children are taught to seek calm and detachment.  For Jedi, it's  because attachment & passion lead to the dark side.  The same's true for Vulcans- they learn to suppress emotions because their emotions are too violent to live with.  So Vulcans have the raw power to be powerful force users and would probably fit in well with Jedi culturally, but if they let their guard down, they'd be *very* powerful dark side users.

Edit: To add, their super-human strength and stamina is another nice bonus for a dark-side user.
