Why Is Dealing with the Weak Inevitable to Bring Misfortune and Loss?

The lower you go in toxic social circles, the more your kindness, generosity, selflessness, and compassion tend to provoke the darker side of human nature in others.
The better you treat them, the more greedy and entitled they become.
When you can no longer satisfy their greed or stop giving, they repay your kindness with betrayal, causing harm and venting their frustration.
This is a loss of control in human nature.
