a baby, a pitbull and lindsay clandy are in a room, who kills the baby first?

Lindsay and the pitbull will have a fight to the death to kill the baby first that will result in the total destruction of the earth's surface, causing all know species including the baby to go extinct, but Lindsay and the pitbull will still be standing, and they will realize that there is no longer a point in fighting. Eventually the area will be heavily layered in snow (it just will okay??) and Lindsay and the pitbull will succumb to their wounds, bleeding out in the snow, finally dying. There are no winners in war.
