Cheesypoofs I would hate to have that role lol.
You have to put someone to sleep and hopefully no one catches you for the 15 seconds. Then you have to kill them and hide the body or kill and run which will probably take another 10 seconds to run far away to not be sussed. So almost half a minute to kill someone and maybe get away. I think it's really rare to not run into or be near anyone for that long.
Plus if you put someone to sleep and you cant kill them at the 15 second mark because of someone coming then they can easily rat out the corporate role.
