Why are most humans disgustingly stupid?

I hate that so many people are disgustingly stupid that I wonder why most murderers became murderers. 

If there were no punishment for murder, I would kill everyone around me and everyone I saw in the street and at work. 

And what's even more disgusting is when the fool is convinced that he is smarter than anyone who has ever lived in humanity. 

And what's even more disgusting is when someone wants to impose their own fate on you because they're jealous of seeing you succeed and achieve things they never even dreamed of. 

I now understand why the devil always says "I"—because he wants to prove that he is the one who decides, that he is the one who exists, and that he is the one who decides.

Therefore, I see no harm in living with the devil's thoughts, but under God's control. I'm not saying you should adopt evil thoughts, but when your time comes, God alone will judge you, not your family or friends. So, as long as you are confident in your path, keep going Even if you fall, keep going. The richest people in the world have fallen millions of times. Don't let anyone determine your fate, because the world is full of fools who are convinced they are smart.
