Farouk,
From my lifestyle of growing up Farouk even at this stage in my life. The freedom, choices, and experience that can come from life should be in even that of a Child's life to be a choice that they do and experience. Of course in the realities sake of understanding danger that exist out there in the world should be found out, seen, and heard about.
My experience in life has been a cultivated experience of all kind of good and all kind of evil, and has made me who am today especially with finding out about God and starting to learn and be taught about Him and Jesus the Son of God.
That is the only response can think of. All people including myself will have to live with every experience they have done; including the good and evil that we have done from even that of hating, murmuring about others, and all of those things.
There will be only one life changing factor is that of letting God come into your life which God can be seen through all the good and bad in my opinion through this life; and God is good, just look at Jesus Christ in his life that he lived in humbleness, lowly, gentleness, forgiveness, mercy, and also spoke the truth even it cost him the loss of his popularity.
That change is not an easy change but is done by and through faith; being renewed and changed in our mind of the things in earth towards the things of the Heavenly; setting our eyes on the Lord Jesus Christ as our author and finisher our faith.
So that we may die with Jesus to sin in the grave, and be raised again to new life by the spirit and living in devotion towards God.
In my best estimation.
