It's not that Scorpius. I know it's not canon and so this death doesn't count. However, Yang has killed in the past. I still can't get over the fact that Team RWBY literally threw a lot of faunus off that train and let them get torn into piece by Grimm and seem to be able to sleep well like if nothing bad happened.

Yang killing Tifa simply brought back those thoughts about what Hunters are meant to do.
