That’s a demand.

Him actually going to prison would be a consequence if it ever happened.

Also two things can be true at once, wanting consequences and those consequences accelerating something can both be true.

Speaking from a purely technical viewpoint I’m not sure how you get acceleration from this assassination. What would accelerate exactly?

When the optimal solution failed, and it did fail, Trump avoided prison by becoming president, then the next best solution is NOT to surrender. That’s just dumb. Trump becoming president is accelerationism, him becoming dead is a step towards return to normal democracy.
