Went in front after outcast turned back filled with distaste (8)
I believe the answer is:
repelled
'filled with distaste' is the definition.
('repel' can be a synonym of 'fill with distaste')
'went in front after outcast turned back' is the wordplay.
'went in front' becomes 'led'.
'after' is a charade indicator (letters next to each other).
'outcast' becomes 'leper' (leper is a kind of outcast).
'turned back' is a reversal indicator.
'leper' backwards is 'repel'.
'led' put after 'repel' is 'REPELLED'.
(Other definitions for repelled that I've seen before include "Drove away" , "Forced or drove back" , "Caused disgust" , "Fought off" , "Driven back" .)
