I wanted to resist...but read enough spoilers on various other live
journals to know what happened, so I ended up looking at the raw
anyway...I could seriously hate Light (Raito) for this. His genius lies
in manipulating others, and he seems to have manipulated them perfectly
this time. I admired the way in which he managed to read into what
everyone around him would do - what I don't want to forgive is the way
he manipulated Rem to do what he wanted. I can only hope something he
has overlooked will backfire on him.
...even if the eraser twist from the pilot is also canon for the manga, Rem won't return...so that was unforgiveable...
