'eden's crime categorically' is the definition.
I can't judge whether this definition defines the answer.

'involved radical rift' is the wordplay.
'involved' indicates anagramming the letters (involved can mean confusing or complex).
'radical'+'rift'='radicalrift'
'radicalrift' is an anagram of 'FRATRICIDAL'.
