Firstly, some people have no passion when they are doing things that they have no direct relationships with. For example, in the video, the deliverer of the Johnny Express on the spaceship has no passion towards his own job at all. He did nothing at all except stopping the spaceship. The things in the spaceship were never organized, rubbish were all around on the floor and the deliverer was sleeping on the sandbag. This implies that some people have no passion when they are doing things like their jobs.
Secondly, some people are not considering the consequences brought to the others. In the video, the deliverer threw and kicked the juice can away. He did not care or realize the serious consequences brought by this--buildings like Mcdonalds, banks, malls were crashed by the rolling can, residents were killed on the road, in their cars and at home, prosperous cities were destroyed and turned into plane earth. The receiver of the parcel, ironically, was kicked into the space with the can. Therefore this shows that some people are not considering the consequences brought to the others.
Thirdly, some people deceive themselves after causing serious consequences. When they do not want to take the responsibility of the consequences, they chose to let themselves to believe that they have done a really good job. The deliver in the video chose “succeed” for his mission after losing the tiny parcel without hesitation, even though he failed the mission--neither has he found the receiver nor given the receiver his parcel. He was not even sure if the receiver received the parcel or not, if the receiver was still alive. This proves that some people deceive themselves when they do not want to take the responsibility of the consequences they have caused.
As a conclusion, due to the above reasons, one possible theme in the video “Johnny Express”, is that when people are doing things that they have no direct relationships with, they are not responsible for it.
