Summitting — it is one of the primary goals in mountaineering.

Logically speaking, it does not make much sense. Mountaineerers often deliberately and willingly choose hard ways rather than just trodding up to a summit. If you just want to summit, then why don't you take the easiest way? Alternatively if you want an excitement of the challenge, then as soon as you finish the difficult part of the route, you should be ready to descend to a safety, rather than stretching to the summit via comparatively easy path, braving a potential of associated risks.

However it seems climbers are not such a logical creature…

Climbing on granite in Cornish sea-cliffs is arguably the best in the country; only the potential down side is Cornwall tends to be wet. The weather is always a gamble, and this time it turned out to be … marvellous! Out of 12 days we had 2 days of foul weather and 1 showery day, and that was it. It could not have been better, really.
