I think intent matters a lot. If you lie to me to take something from me because you want it, that's worse than lying to me in order to prevent me from going somewhere you know someone is waiting to take something from me.

I would never thank you for lying to me like a scammer would. I might thank you for lying to me like a parent would though.

Intent matters. Why you are lying to me is more important than the lie itself in my opinion.
