Hatred doesn't start to be kind (7)
I believe the answer is:
version
'kind' is the definition.
(I know that version is a type of type)
'hatred doesn't start' is the wordplay.
'hatred' becomes 'aversion' (I've seen this before).
'doesn't start' means to remove the first letter.
'aversion' with its first letter taken away is 'VERSION'.
'to be' acts as a link.
(Other definitions for version that I've seen before include "Something a little different - so riven (anag)" , "Rendering" , "Rendition" , "Description from a certain point of view" , "Adaptation" .)
