This last piece which is the "Umbara" arc was an excellent story to watch from ONLY a Republic perspective. While the images of the Separatist Umbaran technology was extraordinary, the reason why the Umbarans chose to join the Separatists remain elusive in "Darkness on Umbara", "The General", and "Plan of Dissent"
(Image of Umbaran Ships allied to the Separatists)But in this Umbaran story arc, there was contentious behavior displayed the Republic Grand Army Clones. Insubordination and countermanding orders of the "Jedi General" named General Pong Krell, who was aloof on the causalities of his men. Nevermind the fact that many Umbarans defending their planet, their homeland, their livelihoods were dying, too. Guess their lives were not worth it to either the Clones or the Jedi General Pong Krell for that matter. Just killing "Seppies" was the mission! Umbarans are living sentient being too!
Throughout this Umbara story arc, the contentious issue was Clones having self-preservation and autonomy opposite to Jedi General Pong Krell who seems to be having emotional conflicts on what side of the Force he was serving -- Light Side or Dark Side. Neither side listened to each other. The end results as seen in "Carnage of Krell" proved disastrous for both the Clones and Jedi General Pong Krell.
From a Separatist POV: Hey what you Republic guys do to your Jedi Generals are your issue. Insubordination and mutiny is par for the course when dealing with Clones. They emotionally get tied no matter HOW MUCH psychoactive brainwashing programming is implemented. While effective, just like birth control, there is a 99% level when used properly. Were the Clones really used properly for the mission?
Then there is your Jedi General Pong Krell, to us, we care less where he leads his men, but we find out at the END of the entire Umbara story arc, there were inklings of connections with our Head of State Count Dooku. Wait, while it does not seem that it would be beyond Dooku to build his own deal, but still, the warped belief to be a part of the Separatist crew with first fighting with evil monologue, not outright murdering Clones like they should be if you hate them so much and find them defective, then allowing yourself to be imprisoned by them? Those are not the way Separatists fight!
Here is what we Seppies think of your "Carnage of Krell" episode:
