From what I've read of the spoilers, I can confidently say, he is a bad guy.
Everything horrible that happened in the 1st timeline, you can trace back to him (intentionally or unintentionally)
He definitely deserves the ending he got.
Minor spoilers:
(Just to clarify, he is not the villain of the story, but I'd argue that he caused way more pain and suffering than the actual villain did.)
Don't like the emperor that much. He's not a bad guy but definitely not a good one. I can understand since he's the king but still he's so crafty and annoying at times. I do miss Trovancha though that country was just so beautiful.
