In many industries and fields, speaking the truth isn't well-received because lies align with the beliefs of the masses and serve the interests of those in power.
Being truthful comes with suffer and hatred by people, but that doesn't mean that you will be killed because we need truthful and honest people to make the world a better place. It's good that we don't become liars because we are scared of what people would say or do to us. If not we will become cowards. The wicked people hates the truth.
