If God is benevolent, why bother about him? If God is evil, why bother about him?

But if God is both benevolent and evil, isn't him very very similar to how human beings are? And thus, why aren't we bothering to dam the flood of evil inside our hearts instead of theorizing evil as an external force?

We hold a spectrum of goodness in our hearts that ranges from pure evil to pure love. And anything in between. So evil exists because human beings exist.
