Correção de texto para cursinho

Olá,

Eu estou fazendo um texto para um cursinho e gostaria de saber se está pelo menos apresentável. Alguem poderia me ajudar?

"Maybe the main problem of Brazil is not corruption in and itself, but the people. The human being is evil by nature. The meaning of corruption has changed since the dawn of the times, and so far, humans being did not come to an agreement about that.
For this reason, we still have a long way to go. And this way isn't expected to be a smooth one. Quite the contrary, it is likely to be a very bumpy one. But, if we are all together, perhaps, we can make it."

Muito obrigado
