If someone is doing something dangerous for show making a joke about teaching someone else to do it falls flat at times, might be taken as a threat. Potential to min. I have made the mistake before, thus I thought it might help others to not make a similar mistake, being forgiving if similar events happen.
I have asked forgiveness from God for the mistake does not equate to I feel justified in throwing stones at others for similar mistakes in communication, word choice. Without sin cast the first stone, see the potential for an if.
Might fend a min, prevent a min, reminder though I am not a lawyer
