In many stories, we often see a clear hero who is all good and a villain who is all bad. These stories show us that we should always try to be good and do the right thing. However, in real life, things are not always so clear.
The article "A teen and a trolley reveal society’s dark side" talks about some tough choices that can show the darker side of people. It makes us think about whether anyone can really be purely good or purely bad.
I believe that everyone has a mix of good and bad inside them. Sometimes people can make selfish choices, even if they usually try to do good things. For example, if someone sees another kid being bullied and doesn’t help, it doesn’t mean they're a bad person—they might be scared or unsure what to do.
Also, good people can make mistakes and sometimes hurt others without meaning to. It shows that while we can strive to be good, there are moments when we might act in ways that aren't very nice.
In conclusion, I think there is a little dark side in all of us. We can work hard to be good, but we also need to understand our own flaws and learn from them. This complexity makes us human.
