To perpetrate only evil will not help one at all (2,2,4)
But I've got no explanation for this one! Could you help me understand?
'to perpetrate only evil will not' is the definition.
I know nothing about this answer so I can't judge whether this works.
'help one at all' is the wordplay.
I cannot really understand how this works, but
'at' could be 'on' (location) and 'on' is present in the answer.
'help' could be 'dogood' (doing good is a kind of helping) and 'dogood' is located in the leftover letters.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
