Bloody choice between sides in galaxy (4)
I believe the answer is:
gory
'bloody' is the definition.
(similar in meaning)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for gory that I've seen before include "Maybe gruesome" , "Steeped in blood" , "Bloodstained" , "Horrific" , "Involving much bloodshed" .)
