Are people inherently good or bad?

I’ve always been curious as to why people act the way they act. The biggest factors of behavior are the influence of the environment and the influence of others. These two forces help shape people from their birth through adulthood. This is not everything that goes into one’s behavior and I’ve always wanted to answer a certain question about mankind: Are we inherently good or inherently bad? This is something deeply rooted in humans and we truly cannot find the answer yet. Examples of both sides can be seen by paying close attention to people. I like to consider myself a very positive and friendly person. I was raised in a very positive environment and my parents have done nothing but love me with their full hearts since I was a child. This is why I like to consider myself good. When I see someone’s struggles or strife, my first reaction is to see if they need help or to find out if there is anything I can do to cheer them up. On rare occasions, I find myself saying negative things about people and talking bad behind their back. Sometimes I even judge a person’s character before even meeting them. This is a side of myself I would consider bad. Mankind is very complex and our behavior changes every minute. What is our inherent nature? Are we essentially good or bad at heart?
