Burning bodies without using it's designated hotkey

Imagine that you are in a room.. alone as a marine.. you are just minding your own business guarding the comms, power, or fooling around with yourself.. it does not matter.. and then the thing just pops out of the ground and you are like "Aw fu**".
At this point in time you know you are going to die, but you don't want the thing to take your form or get your body, so you burn yourself with a molotov and your body can never be used because it's now charcoal.

[Lore straight from the movie]

Instead of using the burn hotkey, I suggest adding a game mechanic where throwing a molotov burns bodies as well as being able to target fire a dead body with the flamethrower to get the same effect.

And allow group burnings? I'm kewl wit dat.

suicide/burn self button pops up when you grab a molly? but not on a hotkey because i'd accidentally kill myself constantly. it'd be even worse than when i accidentally activate nades
