I don’t know; in a scenario like that, it might just be better to keep it in a tank made of bulletproof glass so you can keep it as a pet. It’s still just a goddamn snail. It can’t actually do anything to break anything.
Maybe yeet that bitch out into deep space if it’s that much of an issue. Not too far away; just between stars. You might not be able to track the snail, but you could track the ship it’s in, so you’d always know where to find it.
That way when you do want to die, you can just go retrieve it.
Or just like, freeze it. Liquid nitrogen is pretty cheap.
