Umm.... Random and Uncalled For

I think I might have missed something or both Saturninus and Titus are very ill-tempered and "wanton" men. I am uncertain as to whom I should trust in this play or if I should even take a side. Simply by "barr'st"ing his father in Rome, Mutius is killed point blank with no remorse. Saturninus is ridiculous in punishing Titus for going against... oh wait never mind he just does. Furthermore, he decides to marry Lavinia, and a page later decides he's moved passed her and now wants Tamora. On that note, even Tamora is extremely vindictive and deceitful in her plan to kill Titus and his remaining sons. Overall, I have no earthly idea what's happening so I'll post a picture of what I think will happen next.
