I believe that society has a unwritten contract. A contract that states that we are all here on this earth as a society, and we should all practice doing whats right as humanly possible.
A teachers contract is to teach their students, a parents contract is set examples for their children. Police contracts, enforce the law.
Murder is not part of any contract
When society breaks these contracts hate, anger, racism and death are sure to follow.
Gardeners have a contract too
There is no room for Hate or anger in our world, it's all about loving, sharing, giving, and growing.
