He Was Busy Fighting A Enemy, He Then Sees You, He Notices You Might Die But He Doesnt Really Care Since Everyone Else Evacuated Town So It Wouldnt Matter If One Person Died, So He Continued To Fight And Then When The Fight Was Over He Overkilled it. He Then Walked To You And Said

Why Would You Just Stand There? That Was Stupid. You Coudlve Died. Why Didnt You Evacuate Like Everyone Else? You Risked Yourself. It Wouldnt Matter If One Person Died But Still. That Was A Incredibly Stupid Move.
