Remorseless training inept men to accept Information Technology (10)
I believe the answer is:
impenitent
'remorseless' is the definition.
(thesaurus)
'training inept men to accept information technology' is the wordplay.
'training' indicates an anagram (to train can mean to grow something into a shape).
'to accept' indicates putting letters inside.
'information technology' becomes 'IT' (common abbreviation).
'inept'+'men'='ineptmen'
'ineptmen' anagrammed gives 'impenent'.
'impenent' going around 'it' is 'IMPENITENT'.
(Other definitions for impenitent that I've seen before include "hardened sinner" , "Shameless" , "Unashamed" .)
