Torment as you plot evil (7)
I believe the answer is:
bedevil
'torment' is the definition.
('bedevil' can be a synonym of 'torment')
'plot evil' is the wordplay.
'plot' becomes 'bed' (bed is a kind of plot).
'bed'+'evil'='BEDEVIL'
'as you' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for bedevil that I've seen before include "Bug" , "trouble" , "Cause difficulties for, like Satan?" , "torment" , "Worry, harass" .)
