YES! I have several hobbies including hill walking, and urban exploration and have no problem with calculated risk... I have fell walked in the dark myself solo, and it is a VERY liberating experience! as long as the risks are calculated and basic precautions are taken there is NOTHING wrong with a little risk!
these people were just IDIOTS, Scafell can be more dangerous than Snowdon - FACT! and setting off without a map and compass is just stupid in the extreme!
