i dont understand the fear of love. jefi fears something bad going to happen in love
Jedi don't fear love.
They however do know what can happen if a Jedi becomes emotionally attached to someone. It can effect their judgment and can lead to the dark side, out of fear of losing the person or that person can be used against the Jedi...
Vader would of never have existed if Anakin wasn't afraid of losing Amidala. In fact it was his drive to somehow cheat death because of his love for Amidala that lead him to the Dark Side in the first place.
The Jedi do not fear love any more then any rational person fears a handgun.
