Good exchange above.
In a pragmatic or Utilitarian sense, it is fine if you alleviate the pain of an outcome.. I.E. you're a member of the Underground Railroad and KKK comes to your house asking whether N!gger Jim is around, and you answer No, OR your father has no-tolerance towards drug-users and Marijuana has been key in enhancing your social life and appreciating the finer things, and you claim not to be using it. You save a life to preserve happiness and sacrifice your honesty in the process. More positive than negative. But it depends on perspective.
I'll tell you one obvious thing. It's inevitable that you will lie. Let's just focus on limiting it to better situations I.E. Keyless Entry's latter example.
But by the Categorial Imperative from that Kant deutszchephag, then no. Telling the truth is bread and butter and even if it leads to some sort of punishment, then you are still morally innocent.
My question is if you use a lot of sarcasm, or you simply don't give a phuck about a situation, i.e. your friend (female) asks you if you think she's pretty, but she's shallow as phuck and you don't give a dam or if you're enjoying yourself in college.. then is it aight to lie? Considering you put no merit or thought into la respuesta?
