He's a shady manipulative asshole who knew how Param felt for him but still decided to play with him. And it doesn't seem like he has genuine feelings for Param rather he's more into going 50 shades of Han with him.

Yes he did. His existence is a problem

Personally i don't think he played with him. Teased? Yeah. But still doesn't explain the hate that he's getting. Also, keep in mind that's just an assumption, we don't know enough to say that he doesn't actually like param.
