RE: What would you have done?
Unfotunately this type of stuff does happen what you do next is how you will be judged. 1st: An animal that is run completely through its body cavity by an arrow will almost always die. 2nd: A hit like this throgh the guts will take awhile to kill the animal but will eventually. 3rd: Don't push the animal back out of the area and let the animal bed down and die. 4th: Come back with friends to track or search depending on the sign. Extra sets of eyes are always better. A few years back I unfortunately gut shot an elk after realizing the hit was no good we backed out and returned the next day to find the elk dead a few hundred yards away.
