Jerk or Justified – Airline Edition

Was he being a Jerk or are his actions Justifiable?

A video recently caught the attention of the internet, that shows an incident that happened aboard an American Airline plane. A man was seen visibly nudging, or soft punching, call what you want, but he was upset the passenger in-front of him put her seat back. Now — he is sitting at the very back of the plane, therefore his seat can not recline. Is that the reason he decides to punch the seat of the passenger in front of him? Because he couldn’t recline? Maybe? or it’s because he doesn’t believe reclining your seat on a flight is justifiable at all.

Here is a video to give you a better idea of what exactly happened. Now — based on this guy’s actions in the video is he a jerk or is it justified?
