There’s one on Miranda’s loyalty mission where a merc’s trying to act tough and convince you to walk away, you give miranda a look, promptly start shooting a crane that drops a crate on his people behind him, and then she shoots him I think. That and the weirloc one are what I remember most. Interrupting rambling assholes with death is my favorute. 😂
Tough call between Headbutting 'Brag-atog' Uvenk, defenestrating the Eclipse merc, and shattering Kai Leng's sword before gutting him for Thane (or torching the Weyrloc windbag). Punching Zaeed for being an ass on Zorya was also pretty satisfying.
Favorite was the Schwarzeneggerian “You’re working too hard” electro-stab! It is the perfect example of ME2’s renegade interrupts mostly being 80s action hero moves, with a few nasty bits scattered around.
Most cathartic, though, was breaking Lang’s sword for a proper “fuck you” send off near the end of the game.
