This is obvious. But I do think that the way environment is experienced and interpreted is guided by original personality traits, however it is popular to deny that nature has any effect and nurture is everything. Also have noticed this point of view when it comes to dogs ... especially pit bulls or other violent dogs.
It really is. It is very bizarre when I see people absolute flip out because someone points out that a dog that was bred to be violent ... actually becomes violent. And of course I know it isn't just pits that will attack (I'm looking at you chihuahuas!) but they combine that instinct with power and size and now you have a real problem.
It's hard for people to understand because it's not all-or-nothing. There are plenty of "bred to be violent" dogs that will go their entire lives without doing so. People see that as proof that there's no increased risk, but that's not how statistics works.

Most dogs spend almost their entire lives docile. Those bread to be violent are ones that have high odds of a moment or two of uncontrollable violence.
(And if you look, it's almost always because they have a chihuahua or pinscher ancestor.)
