Greed
Greed is commonly seen on the healthy side of the wall. Because of their prosperous circumstances, the citizens tend to care for themselves and refuse to acknowledge the calamity on the infected side of the wall. This can be seen when families are left behind or resources are stolen from the infected.
Self-Preservation
This is common on the affected side of the wall as a struggle for survival. There is barely any resources and the fear of being killed every day by the militia. The ultimate goal is to make it to the healthy side of the wall without being caught; however, the struggle to get through waves of militia and raiders proves fruitless. Self-preservation is the only effective mode of survival and sacrifice is necessary for the well-being of yourself.
