Fear and logic can look the same from the outside when logic dictates caution. Do you "fear" fire? You understand it, and know what you can and cannot do with it. Yet your aversion to ever letting it exist outside of very tight controlled scenarios, and perhaps panic if you saw it spreading uncontrollably quickly, would look an awful lot like fear to somebody who didn't understand what fire was.

I think the main difference is that fear is an emotional response. And this important because emotions can often misguide us are also easily exploited. For instance, racism is often a product of fear. People see some group of people engaging in crime at a higher rate than usual, and start to fear all people of this group as criminals even when that fear and prejudice is completely unjustified. And tyrants since time immemorial have used "fear the other group" as a rallying cry for self righteous horrible acts in the name of a better tomorrow that never comes.

So in your examples is it primarily fear driving behaviors, or primarily logic/rationality?
