That's like asking why "pathological" and compulsive LIARs are so obsessed with LYING..
As it's also all "BS" when LIARs LIE...
Some are so obsessed that even when caught red-handed, they continue to dig their lying holes deeper instead of doing the right thing. For example lying about a
"blank" COVID vaccine shot card and then getting caught red-handed by others:
That's a blank appt card. They schedule your 2nd shot.
You would know that IF you received your first.
