What do you brag about?
It's human nature to brag, that's why humility is considered the highest form of spirituality, or at least, I personally think so.
If you're beautiful, and you will know by people's attention around you, you tend to show off your beauty. If you're smart, you show off your knowledge. Even if you're religious, some people tend to brag their piety thinking that being "good" makes someone "better"!
This superlative consequence is almost always meaningless! Seriously, think about it, do you think that someone being more educated, smarter, prettier, more pious, more well-mannered, more ethical, taller, shorter, thinner, fatter would make anyone any better of a person?
At least piety SHOULD in theory make one a better person, but in practice, the second you feel that you're "better" because of [insert your favorite adjective here], then you're no better than anyone.
Yes, that includes the worst humans in history!
It's easy for nations to feel this futile pride. We're better than "them" we don't invade other countries, and we don't kill innocent people.
History has shown that EVERYONE has the blood of the innocent on their hands. Every single last army in the world.
Truth is, no one is better than anyone. That's a fact that many people struggle with. They might even understand it. But they simply don't get it.
"Verily the most honored of you in the sight of god is the most righteous/piety among you"
Or so it should be in the Islamic faith. No one is better than anyone else. Or nation to any other with only one thing. Their piety and that's something no one can measure. There's no external way to see this or feel it in a person. It's an internal feeling.
Humility might be a way for the person to feel it and connect with it, it might be our guide to help us be better than ourselves. Not others. For the second we feel that we are, we're not.
So every time you hear someone in the movies saying "I'm not going to kill you because I'm not like you" then he's not killing for the wrong reason. He's not killing because he feels superior. It's good, but it might be a better thing not to kill because it's against your principles. Not because you're better than the murderer.
Perhaps this will reach a pretty person, and get them to realize that no one is better, or a smart person to make them realize also that they're nothing better than anyone else.
