Coaching liability

Criminal liability?: practically none.
Other liability?: clear conscience.

Sometimes a coach does not speak and is not able to speak directly to each person.
Sometimes he speaks publicly, very generally.
Example:
Saying that “it is worth getting out of your comfort zone” someone may start walking around in just their underwear, and this will obviously not be the way to fulfill sports dreams, but the way to participate in adult films. This can also be a kind of justification for someone to fulfill their hidden dreams: “Because the coach ordered” (an attempt to clear one’s conscience, an attempt to shift responsibility for one’s actions onto another person, acting contrary to one’s conscience).

Can the coach in this example have a clear conscience? (he does)
Can a person who follows the coach’s advice in this way have a clear conscience?
