I once decided to climb Half Dome cables despite clouds that could have brought a thunderstorm and electrocuted me. On the other hand, I feel that 1. having had the experience of climbing Half Dome was a great asset to me in two decades since, 2. due to various life circumstances since I would probably not have come again later and 3. By now I am probably too old and busy with other priorities to manage requisite backpacking trip with two full days of hiking. So in retrospect, I don't regret my decision and, had it not worked out, well I would not be around to regret it. So long as one goes into things with eyes open, I am not going to judge.
