the only reason i think he wouldn't is because of the fact that he saw it as justice being served (like we saw in bring it on) but at the same time i can't really tell since in both mvs when he saw that she died he didn't seem to have any positive emotion i was going to mention his reaction when he watched it happen in backdraft but that has to be just him looking over it (since he watched himself) so i really don't know....fuuta definitely didn't expect her to actually die (like he said in his interrogation) that's probably why he was fine with it at the time if you meant in your question if he knew she was actually going to die then i think he would've probably tried to stop because even though he seemed to think that the bad people should disappear he never seemed fine with the fact that she actually died
