Sasha Alexander wanted out of her contract because all the main actors were working 100+ hours a week, 7 days a week. She wanted to spend more time with her boyfriend [later husband] Edoardo Ponti [son of Carlo Ponti and Sophia Loren] who lived and worked in Europe. Donald P. Bellasario - creator, executive producer and showrunner - decided to let Kate exit with a bang - literally.
Sasha is currently starring in 'Rozzoli & Isles' [renewed for a second season] and is pregnant with her second child with Edoardo.
Kate didnt want out... she got shot by Ziva's brother Ari, unless you mean the actress that played Kate (Sasha Alexander). Um that I have no idea about, she probably got other job offers if she did want to leave the show...
its because she did not realise all the psychical work related to the show and could not keep up with the standard's for the show, so she left
Because she died
