Two choices…

Drop him off at the bottom and let him claw his way to the top…

Or,

Drop him on top and let him bask in the glory of reaching the pinnacle of Devil’s Tower. Maybe even put his Arch de Trump up there with some gold leaf for him to apply. Then he can shout to the world that he is the greatest Devil of all time….

Then… after he dies happy up there, bomb the hell out of it. Leave no trace. Only the legend.
