Pray, as Goth murdered philosopher (10)
I believe the answer is:
pythagoras
'philosopher' is the definition.
(Pythagoras is an example)
'pray as goth murdered' is the wordplay.
'pray as goth' can be anagrammed to 'PYTHAGORAS'.
But, I'm not sure how this is indicated.
Can you help me to learn more?
(Other definitions for pythagoras that I've seen before include "Greek with a theorem" , "Greek philosopher/mathematician" , "theorem by this guy" , "Ancient mathematician" , "Ay to graphs (anag) - 21 3 17 theorist" .)
