Think responsibility. Even if you watched the thing roll you don't have a lot of responsibility. Only a little. Because as you said that I am involved.
Let's say there will be an investigation because of criminal liability by inaction (civil law jurisdiction). First you aren't in guarantor status (one example is the surgeon during a surgery), and second if you explain that you tought it through and showed that the what-if case is dangerous, you won't be punished for inaction.
So, no, it does not really matter that you are involved by being there.
And now I am sure that many people could develop post traumatic stress disorder because they feel they have failed to save people. I am sure that these people can be helped if they are shown the possible outcomes of action and inaction, especially that action is often more problematic than inaction.
