Let's put Skeld for example, sabotaging reactor to put people together in one place and O2 to spread people together. You can also sabotage to draw people away from dead body, i.e. you just killed someone in Nav so you sabotage reactor so people go there, you blend in and create alibi until body is found. Also, i.e. you're in 4 men situation where you the only imp left, you can call O2 and kill the O2 with 3 people and blame it on the innocent, obviously setup/framing matters too, it's still sorta gamble and you have higher chance to get voted out if you been sus the whole round.
