That’s funny! but if you want to know how to solve this problem every time, even when asking one single question, just ask this question:
“If I ask the other guy which is the correct path, which path will he tell me?”
No matter who you ask, both of them will point to the WRONG path, meaning the correct one is the one they DIDN’T point to. Here is the logic.
For the sake of argument, let’s assume the correct path is the right path. When you ask that question, if the person is the truthful one, he will be honest and say the left path. Because if you ask the liar what the correct path is, he will say it is the left path (which is false). Now if you ask the liar what the other guy will say the correct path is, he will lie to you and say it is the left path (which is also false, the truthful one will tell you it is the right path and not the left).
yeah, it could be the liar guard’s desire or prime directive to send you down the deadly path. to him that could be interpretated as the correct path. especially if these are automatons working off of some machine logic. like, they don’t even need to be out to get you, that’s totally something that bad code could do on accident.

The liar responds “I don’t know”
and also, using “correct path” instead of “right path” will be less confuzzling because english words can have multiple meanings and are the dumb.
You should even specify “path to the castle”, because there isn’t technically a “correct” path.
This puzzle was used in more than one place than in Labyrinth. I played video games where they had that puzzle (Ultima 6 had that).
What is the quest was to die asap. And everyone the party meets just refused to kill them?
