Knowing our purpose here on earth

In my entire life,i have devoted time to learn so much about GOD and mankind,i have gained understanding,knowladge and wisdom of both GOD and man,
man thinks so much about himself,every thought of a man revolves arround himself alone.
a young man doing busness with his friends has been douped and betrayed,his hard earned money mischieveously taken away from him by thesame poeple he trusted,GOD why?
You don't visit men in the scene of their crime,rather you let them go,you give them long honour and the oportunities of defending themselves,you are so merciful to a man,you even made him with so much will of himself,which he has even used against you,these were what some poeple looked at today and concluded that you can never let the man you created be burnt and be turmented by fire,but then every sin counts,every good deed counts equaly,choose which to do all is for your benefit and detriment.
