Agent left in American vice squad finally revolted (8)

I believe the answer is:
repulsed
'finally revolted' is the definition.
The answer and definition can be both to do with human feelings as well as being past participle verbs.
Perhaps you can see a link between them that I don't see?
'agent left in american vice squad' is the wordplay.
'agent' becomes 'rep' (short for representative).
'left' becomes 'l' (common abbreviation).
'in' indicates putting letters inside.
'american vice squad' becomes 'used' (I can't explain this - if you can you should give a lot more credence to this answer).
'l' put into 'used' is 'ulsed'.
'rep'+'ulsed'='REPULSED'
Can you help me to learn more?
(Other definitions for repulsed that I've seen before include "Caused to feel intense aversion" , "Driven back in preludes" , "spurned" , "Beaten back" .)
