Yes! It also explains the partial "memory loss". He has forgotten Nara's betrayal and yet has flashbacks from their bed scenes (which were with "bad" Tasara). I think that's the best idea "bad" Tasara came up with...
In my own understanding, the real Tasara and the 'evil'(according to Nara) who loves him merged that's why he wants to kill and love Nara at the same time.
