I would say No.
Spoiler alert, obviously.
Maybe he has been blind for his son, but I think he tries to save him, as he is his father. If you read a little more of your quotation, it should become a little clearer:
Darth Vader: What is thy bidding, my master?
Emperor: There is a great disturbance in the Force.
Darth Vader: I have felt it.
Emperor: We have a new enemy, the young Rebel who destroyed the Death
Star. I have no doubt this boy is the offspring of Anakin Skywalker.
Darth Vader: How is that possible?
Emperor: Search your feelings, Lord Vader. You will know it to be
true. He could destroy us.
Darth Vader: He's just a boy. Obi-Wan can no longer help him.
Emperor: The Force is strong with him. The son of Skywalker must not
become a Jedi.
Darth Vader: If he could be turned, he will become a powerful ally.
Emperor: Yes. He would be a great asset. Can it be done?
Darth Vader: He will join us or die, my master.
(as seen here)
His first answer is no "... and we should stop it", it's more like a "yeeees, it's been tickling, but, ack, forget it..."
He, IMHO, underestimates him for purpose. He wants that his master won't believe that this little boy will ever be a menace.
Then again Vader pretends being dumb and has to search his feelings. Like threatening, force feelings and... "that's my son, he will be stronk".
After that Vader truly wants to save him while saying that a kid won't harm anyone. He is saying that Luke is innocent, no target.
The Emperor then states, that this kiddo is more than Vader wants to admit. That's were Vader only sees one option to save his rugrat: Turning him to the dark side. Because then Luke can live - and side by side by his father.
The Emperor thinks that'll be a good deal - the two strongest force users under his command. So he agrees.
The last sentance, IMHO, is more like a platitude. "I'm his father, he'll join me."
And in the end we see, that Vader himself turned to the other side. :)
As Vader obviously tries to save and/or convinvce him to the other side, Vader did not intend to kill his son. Killing would be a much easier option - if Vader had no feelings left.
