In "Romeo and Juliet", how does Juliet feel about Tybalt’s death?

At first she is upset and angry because her husband killed her cousin, but after she realizes that if Romeo didn't kill Tybalt he would have killed Romeo. She then sides with Romeo to be loyal and after that we don't hear anything about her feelings for Tybalt. Most likely she doesn't care much after.
However, in Act 4 - Scene 5 when she is talking about being in the tomb with Tybalt's dead body she mentions at the end of her soliloquy how his ghost will try and get revenge on her. Maybe she feels guilty here?
