NO RIGHT TO RAGE

My classmate and I are supposed to go to this field trip to Kanye West House this undisclosed certain government facilities. The bus arrived, so we all move our butt into that bus. Then suddenly we notice one person is missing, but let's call the missing dude Six-pack-Muscle-Macho-Man. Then on of us, caring as we were, call that Six-pack-Muscle-Macho-Man. That dude specifically tell us to go without him, since he just woke up and he don't want to delay our bus. But somehow,the bus never took off. The classmate decide to wait for Six-pack-Muscle-Macho-Man because all the girl are his fan club's members. The bus was delayed quite long time. When finally Six-pack-Muscle-Macho-Man appeared in the bus,  bursting with rage, he half shouted angrily " didn't I told you all to just go, why didn't you all go??!!! asshole!" ok, I made up the last word..but I'm sure he half wanted to say it.

On this side : The fan-club's members wait for Six-pack-Muscle-Macho-Man because they care about him

On the other side : Six-pack-Muscle-Macho-Man clearly and specifically told the classmate which majority are his fan club member. to go without him because he don't want to be a burden and delay the bus any longer.

What do you do in this kind of situation? Who get the blame? Who is the guilty party?

But that morning Six-pack-Muscle-Macho-Man was filled with mindless rage because he become the burden. Did he have the right to be angry? The classmate did it out concern for him. 

I personally believe he need to calm down, he don't have any right to be angry,the classmate hasn't done anything wrong to him. 

I put the blame on the classmate exclude me of course. They should left him. Six-pack-Muscle-Macho-Man specifically told the classmate to get lost to go without him..

What's your opinion??
