Nothing Stays Good in this World!

Most people while watching movies look for something inspirational. Something so motivational that will charge their inner spirit and make them get up and do the things they always wish to do.
Same thing happened with me when I was watching Batman V Superman: Dawn of Justice. But it wasn't the quotes from Bruce Wayne or Clark Kent that got me thinking. But the one Superman says after rescuing Lois Lane.
'Nothing Stays Good in This World'. It's awfully true. No matter how hard we try to be good and do good to the world, the world still conspires against us to become selfish and Lex Luthor of our own world.
The thought that always amaze me is that every child was raised to be a good human in this society yet they end up being the jerk they always hate. No offence but even though we think we are doing good, we will still be going to be hated by someone for the very same reason.
So what is it that makes us heroes in our own eyes but monsters in others?
In my experience it comes down to a very simple logic. Black and White. Good and Evil. Heroes and Villains.
Every human being has two sides and every second we choose to act on that side. It that simple.
We were given free will by god yet we always chose the side that will give us simpler results. That's, selfish choices.
I've been facing negativity all my life, even while typing this, yet I always try to chose the good side. Its a difficult choice and I make it every single second and I'm being hated for it every other second but that's what makes me human. That's what makes me realise that I have a free will and I didn't chose what everybody expected me to.
Nobody stays good in this world. But we can try not to be the bad version of our self. Because when the judgement day will arrives, we will be asked 'What good and bad you did in this world?' And I want someone to be proud, not GOD, but myself.
