I have told my sons and grandchildren on numerous occasions that the most valuable things they can learn from my example is what NOT to do! Sometimes that is more valuable than what TO do. My dad used to tell me that I should always learn from the mistakes of others since I would not likely live long enough to make them all myself.
I am always pleased if others can learn from my mistakes. I'm not very proud of some of them, but I am thankful to have survived them and to have learned from them myself along the way. The older I get, the more I try to pay attention when others make mistakes so I can avoid the consequences of making them myself. I appreciate those who share their experiences that provide an opportunity for me to learn from them. Sometimes people seem to brag about their mistakes and wear them as a badge of honor. I don't get the feeling that the OP was doing that here.
I, for one, appreciate his willingness to share his experience and emphasize the results by posting those pictures. A picture seems to have more impact than just words. If that had happened to me, those pictures would be posted up directly in front of my reloading equipment on a permanent basis. I have cleaned up after many hundreds of vehicle crashes that involved a "touch" or more of alcoholic beverage. I retain a few pictures of those as a reminder to me of the possibilities. Of course, these things also happen without the involvement of alcohol. You don't have to be under the influence to either be careless or make a mistake, but the consequences are the same either way. Thanks from me to the OP for posting this graphic example of consequences. But like the consequences of serious car crashes, it's easy to see them and think that I would never do something like that ... it won't ever happen to me ... but that kind of thinking will never be of any benefit to those who think that way!!! Forewarned is forearmed ...
