I think I will only give A factor that affect human's behavior
The Place where you was raised
This includes the persons that surrounds us, the behaviors we are witnessing, the things we own and the things we don't have
This mainly affect our behaviors, the persons that surrounds us and their behaviors was the biggest contributor of our behaviors.
If all those persons that surrounds us we probably could get their actions
Well I do mean the way for their actions, their way of thinking, their way of making decisions and many more in their behaviors. If the people surrounds us was full of liars, we probably would end up a liar as well.
Also the things we own and not was also a factor, given that we already end up being a greedy person (greedy persons surrounds us) We probably would not be satisfied on the things that we have. We probably would end up behaving and committing evil intentions.
Well not all of the persons end up in this situation but I can roughly say (base on the people that I know) that there are 80% of the people that I know fall under this factor
