Should I feel bad for thinking this is funny?

Last year, my father-in-law and I went backpacking at the Mountain Bridge Wilderness Area, which contains the familiar Caesar's Head overlook. Since I met my wife, he and I have been backpacking several times a year. On this particular trip, he and I hiked to camping spot D5, which is down on Marshall's Creek. Upstream of us was Raven Cliff Falls, another really popular destination for day hikers. The trip down the mountain to the campsite was obviously easier than the trip out. We took the long way out which took us back up the mountain on the other side of the river and then to the swinging bridge over Raven Cliff Falls. We had taken this trip before but did it in reverse, where we came down the mountain from Raven Cliff Falls. We knew that this way would be tougher. One of the first obstacles was a wire "bridge" strung across the river. This consisted of one wire to step on and one wire to hold on to. That was exciting and fun with a full pack on (even though the "full" pack for us on this trip was less than 20 pounds since we were thru-hiking). After a full morning of hiking, we made it to the top of the falls. We decided to eat lunch here and found a secluded spot next to the river to sit and rest. We took our boots off and enjoyed the cool water too. We had finished eating and were resting before the rest of the 12 mile trip to the next campsite.

Thats when it happened. This guy and his family decided that where we were was the perfect spot for them to eat lunch too. Literally, with all of the space on the river, they park between me, my gear, my father-in-law, and his gear. He was a jerk too, was rude to his family and he overruled his wife's concerns about parking right in the middle of where we were. We thought it to be quite rude. We took a little consolation when he slipped on the rocks and took a really hard fall right on his butt. We promptly started packing our things. Then, the guy had the nerve to ask us about the trails. He didnt get the 2 dollar map? We told him that the hike ahead was long and strenuous. He decided that he would continue going forward and that his family would backtrack to the car and drive down the road to where the trail met the road. This idiot (if you allow me to call him that with the little knowledge I know of him) did not have any hiking gear and had drank half of his water already. Personally, I dont think he had enough water to take the backtracking route. We voiced our opinion about how difficult and long the trail was (since we had just come from that direction and had taken it in the other direction during a previous year. He insisted on going forward.

Fortunately, with his decision we had our leave and headed on down the trail. I guess I took a little solace in knowing that he was going the opposite direction and that his family would have no chance of catching up to us. We made our way to the next campsite just before dinner time and settled in for the night. We were very tired and had covered about 20 miles in a day and a half. We chose this spot (#18) since it was only 1 mile hike back to the truck (even if there was 800 feet elevation change to go up). The next morning we were ready to head home and got up earlier than normal and got out of dodge.

I dont want to spoil the ending, but, the road we were heading down crosses the trail that the idiot had left for. We were going to pass by the spot where his family was supposed to meet him. For a moment, my father-in-law and I joked that he would have not completed the hike by dark and that he would be coming out of the woods this morning. We both were anticipating the sign indicating that the trail crossing was ahead. We would not be dissappointed. What luck in timing. The idiot was hiking up the road back to Ceasar's Head only a few hundred feet from the trail. He had just made it to the road. He was wearing shorts and as I mentioned before, did not have any gear. He must have had a miserable night with no water, the mosquitoes attacking, and then the temperature dropping to 40-50 degrees. Fortunately for us, he wasnt far from the ranger station and we didnt feel the need to stop and help him. I would have enjoyed telling him "I told you so" though. But, we laughed really hard and discussed his misfortune all the way home. I am laughing now. Should I feel bad for thinking this is funny?
