I don't think wishing peoples death and destruction of their property is a very good indicator of personality, or state of mind. But that's just an opinion of course not supported by any scientific research whatsoever. I heard somewhere upon the news of death and destruction a common reaction was to feel sorry for the victims rather than glee because they perceived the victims to have a point of view different to them (not that I am aware any KF actually knows a single victim or what they think).
I'm unsure that budgets actually prevent low humidity and whether or not it rains, but I could be wrong on that too. Perhaps budgets could prevent it raining on the coast and stop hurricanes also, I'll have to look into that deeper.
Imagine feeling glee as a neighbor loses their home, pets and possibly their life and livelihood because he didn't think like you. What a lovely neighbor you must be! It makes understanding why we saw some groups dancing with joy as people leapt to their death from the towers - not because they knew them, just because they were certain they mustn't think like them (without even knowing them) , and therefore, death was totally OK.
Stare into the Abyss long enough and it stares back. Once you start taking joy in others suffering, it is your impulses controlling you and sending you chemicals to feel satisfaction in your depravation. It is only a next step that you'll start lighting the fires yourself to get your kick, after all they aren't really people of value, right?
