i think sabo could very easily slip and go too far and kill someone thats supposed to be an ally. since his brain damage as a kid he's been portrayed as someone who's extremely, enthusiastically violent ("i can crack a human's skull as easily as an egg" while grinning like private pyle) and as someone who has totally lost and forgotten their childhood dreams (Sabo was supposed to write a book about the world and always carried his journal etc. He hasn't mentioned it or done anything to show that he still cares about it since he reappeared in the story)
like the Cobra scene was there to show that even Dragon and Ivankov know that Sabo is capable of going too far. They trust him, but they still had to ask him and check because it's absolutely within the realm of possibility that Sabo just killed Cobra to make people hype for revolution. And Sabo even admits like yeah, well, that part where he died and people got excited about it is cool. I don't mind that.
