Think about the OT. It was established early in ANH that Vader could choke people to death. And yet Vader never ONCE tried it against Luke. Would have ended the fight pretty quick wouldn’t it, if Vader had just choked him to the point of unconsciousness? Well it’s pretty obvious to me that Vader couldn’t because of how strong Luke was in the force. That’s what sets the Jedi apart from the normal people in this universe, otherwise the logic of it would all fall apart.

Vader never wanted to kill Luke because he was Vader’s son.
