Mr. Delany wasn’t seeking a new frontier; he was going on a thrill ride. This wasn’t some honorable attempt to support his family or better their life by forging a trail through the wilderness. He was pursuing some personal desire irrespective of the consequences to his family. That’s shameful.
Had he been seeking exercise, there are a multitude of ways he could stay in good physical condition without traveling to Nepal.
He and his wife likely discussed his trip and agreed on it before his daughter was conceived. It would be shameful if he had gone against the wishes of his family, if they were okay with it it’s not shameful.
