Re: Non-murderers you're meant to dislike or hate?
I'm pretty sure it's because it was the series Pilot that Carlson snaps at Columbo. The Movie pilot (Prescription Murder) Columbo isn't the bumbling character we see later. In the Series pilot maybe they wanted more emphasis on his bumbling or absent mindedness. We rarely see Columbo get reprimanded in later episodes except perhaps in Death Lends a Hand, A Friend in Deed and Candidate for Crime.
