Tbh, I absolutely hate what Paul did, and I'll never defend or support his actions because I genuinely felt bad for Zenith. It was actually one of the reasons I dropped the anime for a while.
But somehow.Paul just has this grip on me as a character. No matter how much I wanted to dislike him, I couldn't bring myself to actually hate him. He's such a flawed, frustrating, and human character that I ended up coming back to the series partly because of him.
