Should our existence be conditioned?

 I use to listen from my grandmother how a boy should react to insult. How should one convert the negative energy for making it positive. But I always saw inadequacy in this technique. Showing a person who hurt us with counter hurting is basically giving credit to our success to that same person and with violence too. It is the negative condition for our existence and what we want to do with our life.

On the positive side, some say I live for my parents, wife, children etc. But what if there happens an event to affect them badly. Can they be source of our liability or source of our guilt? Are not we making them victim of our inability to cope with ourselves even after death.

Then, what is the condition that we should adhere to so that we can live with peace? 

First of all life is not conditioned but death is conditioned. A mistake can cause death and end this life's experience. All those conditioned must be avoided at minimum to live with peace. Life seeks continuity and rest are just consequence of this. Crowd wisdom of humanity is to save itself. Some may name it knowledge, science, art or whatever but they all are just attempt to protect this human race. 

Accepting beauty that life exist is enough for our existence as it exist irrespective of ones' desire to live. How can you condition what is unconditional? How can you then not love what is unconditional? When you love everyone everything like yourself, how can you not find peace and purpose in this existence?
