Cowardice
When you run away from a mad dog or a maniac carrying a weapon, it is prudence… and yes! prudence is the best form of valor…
I might consider respecting an unreasonable thug that can dare to be truthful (regardless whether he is right or wrong)… But for the conniving coward that shamelessly wears a mask to hide his true face… I bear no respect!!!
When you lie or pretend to someone that trusts you… that is cowardice!
Lying, Deceit, Pretense, Treason…. are all close cousins!!!
All of them end in breaking the trust of the one that you got to trusting you…
They all stem from fear and as such represent the worst of human weaknesses… COWARDICE!
