Sure, we have the same power's patron, but two people with a gun use that gun in different ways!

I'm not sure this is comparable to two people with a gun.

Sure it is patron! You can compare anything to one or more people with a gun.

Paris syndrome.

You go to what you believe to be a fancy park filled only with peace, only to find out everyone there has a gun and are killing peaceful woodland critters!

Illusory superiority.

You have a gun. Your gun is a small pistol. You have no idea everyone else has a gun, or you believe that the gun they are carrying is a water gun. It turns out the statistically average person carries a shotgun.
