Pre Vizsla
Who Is He: Leader of the Death Watch, a group of Mandalorian terrorists determined to restore the Mandalorians to their forgotten warmongering way of life.
Why We Think Hell Die: Hes just too much of a villain not to kill. When someone burns down a village for the hell of it, there no chance of redemption there. Also, hes teaming up with Darth Maul. And making a bargain with a Sith Lord is the equivalent of painting a bullseye on your face. Just ask any of the Imperial Officers who served under Darth Vader.
Why We Dont Think Hell Die: Theres still some mileage in his character and hes definitely got the fighting skills and resources to survive tangling with Maul.
How We Think Hell Die: He will eventually outlive his usefulness and Darth Maul will kill him. Other candidates for his executioner in my opinion are Satine Kryze and Obi-Wan Kenobi.
Hondo Ohnaka
Who Is He: A wisecracking Weequay pirate with dreadlocks, an Electro-Staff, and a fondness for betrayal and making money no matter how he has to kill.
Why We Think Hell Die: At this point hes just got on the wrong side of too many people to stay alive for much longer. Hes taken Anakin Skywalker, Obi-Wan Kenobi, Count Dooku and Ahsoka Tano hostage, smuggled arms for the rebel forces on Onderon, attempted to raid a Jedi ship and kill the children aboard, and attacked Darth Maul. A move which will surely come back to haunt him.
Why We Dont Think Hell Die: Hes a popular and amusing character with some great voice work by veteran voice actor Jim Cummings. Also, the Republic occasionally finds him useful and therefore turn a blind eye to his dealings sometimes.
How We Think Hell Die: The final episode of the seasons four episode Young Jedi arc (of which episode three is scheduled to air on Saturday) features Hondos base being attacked by General Grievous. Going up against Darth Maul is foolhardy. Going up against Grievous is damn near suicidal. Either that or the Jed will finally think Sod this and have him killed.
