Is mankind inherently good or evil?

I personally like these questions and ideas. I don't really know why but they call to me and I try my best to answer. As a child I always preferred playing as a villain, I pondered why the heroes always beat the villains and the idea of being a hero disgusted me. To this day I still wonder why I thought like that even though I still like the villains and like to see the villains win. As I think about it more I realize a possible reason why. As a kid I was bullied, I was constantly seen as an outsider and put down. Nobody respected me so the next thing to that is fear. After fifth grade I grew faster than others and kids would fear me. I could then relate to a villain. I liked how in a villains world, people had to be strong and take what they want, they had their own laws and what they wanted, went. To this day I despise the weak, no Im not some cold heartless person. The people that can do something about it and choose not to, the people that hope everything will just work out, you need to take what you want and let nobody stand in your way. But then I have a heroes mentality, I hate politicians and the rich who never worked for a penny in their life and would love to take a Robin Hood kind of approach. I have read many books with connection to humankind being either good or evil. I like the conflict and how it is such a big question. In the book "Relentless" by Tim Grover, he talks about how we are born bad but taught to be good or if you prefer, born relentless, taught to relent. From the time you're a toddler to the time you're an adult, you've been taught to be "good." Being bad is in our basic emotions or feelings, just like if we are hungry or in pain. Little kids from day one are constantly breaking, yelling and messing up things. Most of them are not helping clean it up unless they are told so with consequences. Movies put a bad name to bad/evil. They make villains and even bad people to be ugly, weak and stupid. I hate that too. Some movies like Batman show some gratitude toward the villains. In one quote, batman says he could not live without the joker. There would be no point in it if there was no evil. The media is addicted to evil, death, violence and corruption but yet again, who is not? Don't we all like seeing it? Or there wouldn't be anyone watching it. Deep down our need to be bad is calling out to us.
