I went on a trip with my class in college
How was the trip?
It was a bad trip. We were with a bunch of idiots in a caravan with a captain who hardly knew the roads.
I hope you don't blame yourself for this.  Not everything can go your way. Sometimes you will be in bad situations through no fault of your own.
I hate all these idiots and I'm glad that they had a bad class trip.
I can understand why you were upset, since it sounds like many of your classmates were truly to blame for everything that went wrong.  However, I would advise against holding a grudge or wishing harm on them.  You'll really just end up making yourself feel worse, so it's best to move on.
