Humanity’s biggest flaw?

What do y’all think humanity’s biggest mistake/flaw is

I believe humanity's biggest flaw is that we don't want to work together. Everybody wants to do something different and doesn't want to agree and do what's in society's best interest. Which is why I think this.

probably capitalism and how the system doesnt work properly

Humanity Biggesst flaw is people.

the fact that everyone is hunting for money, even tho the world is getting ruined by capitalism

our inevitable death being slowed down by cheeseburgers

the legal system is the biggest flaw in most countriess

lack of education, creating more schools/schooling opportunities will help the world out so much
