Well when I say that it is to address those that think Eric could STILL be a help for Max in dominating or helping Max get what he wants.Apart from the 'what he should have been from the get go' bit I completely agree with you.
I personally am not into that but if that was a reasonable thing to hope for with Eric then it should have been done from the get go. Since it wasn't, No reason to revisit and try and correct that...
The Eric being good ship has long ago set sail!
