Casualty (6)
I believe the answer is:
victim
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">casualty</span>' is the definition.<br/ ><span class="explanation-format__explanation">(both can mean someone injured or killed)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for victim that I've seen before include "Injured person; dupe" , "One made to suffer" , "Casualty or scapegoat" , "Person who suffers accident or crime" , "Oppressed or suffering person" .)
