I used to think this way when I was miserable and disillusioned with society in general. When you approach life with the assumption that people are evil by default you tend to only notice things which affirm that belief. I’ve since made a lot of changes in my life and gained a new perspective, and I’ve found that I more frequently notice people doing small acts of kindness when they think no one’s looking. Most people want to do good, it’s just that they don’t often succeed.
