I actually don't see him as evil. I see him as operating in a Machiavellian way in a time of war. He skirts the issue of evil, but not directly evil IMHO.Right. Most people seem to think that him being evil is cool. So this show will work for them.
My personal thoughts on Discovery on the whole are still up in the air though. Lorca as a character, or any other character alone, doesn't make the whole series.
