Couple of points to address:
First off, yeah, the guy was in over his head for sure. However, it appears he was attempting a -modest- scramble and took some serious wrong turns...and end up cliffed out. He wasn't trying to be Alex Honnold or anything. Lets not judge too hard, he made a mistake and needed help. He's getting quite a bit of internet shame here, cut some slack.
Second, Snohawk10 is part of the VOLUNTEER organization Snohomish County HRT...which recently lost all state funding. They are operating 100% on DONATIONS right now, and it has been and will always remain a FREE service. This guy called the police and they told him they couldn't get him. It is likely he would have fallen and died if he had been left overnight...without intervention from this FREE, DONATION FUNDED service run by volunteers..
Thirdly, Miles, the nice man rescuing this dude, edited the film a bit. In it, the fellow asks several times if he can bring his bag. The mountain rescue squad is headed back to this area to get his backpack on FOOT. As you can imagine, the pack adds weight, and it is -not- a human. If the pack ends up tangled in the rescue equipment or in the blades of the helicopter, you're going to have yourself a situation. This is just a safety first kind of thing, internets.
