With Palpatine one issue is that trying to fight him and his plans in a visible, blatant way is likely to have him double down. You bring a knife, he brings a gun and all that. A prey animal, when being run down by a predator like a cheetah, has to get the predator to over commit and then swerve at the last second.
Is fighting the sort of thing that hinders Palpatine, goads him into increasing his efforts out of spite, switching into a different sort of sabotage that makes winning another form of loss, or even just decides that we (and other pawns like Grievous) are too difficult a prize and thus something to be discarded like every Jedi? Killed outright when things suddenly go to shit. None of us have infinite value in his eyes and are merely things of some limited convenience.
Its a serious question. This could go a few ways.
Also, its interesting that this is going to be souring the Temple's relationship with the powers that be themselves. Not breaking anything... but the Temple will be naturally inclined to be more cynical in its exchanges. This is a clear cut sign the enemy... if one assumed to be a more banal enemy than a Banal enemy... is within rather than without. They knew the Senate and the mass of wriggling worms beneath its pallid skin was sick but this blatant a move should crack an eye or two that its worse than they thought.
Its a good first step for them and, by itself, that is a good step forward. But it also might lead to more pressure against them in response in the hopes of causing an overreaction.
