in the 1987 Robocop Movie when Dick Jones introducing the His Robot ED-209 & Demonstrating to OCP chairman & Other Staff, ED-209 Kills Innocent Employee Without a Gun.. so my question is is this Malfunction of ED-209 Sabotage by "Bob Morton" to Get Approval from OCP to His Project Robocop or it's Just a Malfunction ED-209?
As far as we know, it was just a malfunction.
You might apply Hanlon's razor to the situation:
Hanlon's razor is an aphorism expressed in various ways including "Don't assume bad intentions over neglect and misunderstanding", "Never assume malice when stupidity will suffice", and "Never attribute to malice that which is adequately explained by carelessness". It recommends a way of eliminating unlikely explanations for a phenomenon (a philosophical razor).
In other words, we have no reason to believe that anybody sabotaged ED-209. Instead, the accident can be explained by rushed development, poor planning, improper testing, etc.
You could go a step further and say that this is part of the satirical nature of the movie, criticizing business practices that favor profit over the safety of the general public, but I'll leave that as an exercise for the reader.
