Found this amazing passage from the Quran =) it opened my eyes:
"Tell them the truth about the story of Adam's two sons: each of them offered a sacrifice, and it was accepted from one and not the other. One said, 'I will kill you,' but the other said, 'God only accepts the sacrifice of those who are mindful of Him. If you raise your hand to kill me, I will not raise mine to kill you. I fear God, the Lord of all worlds, and I would rather you were burdened with my sins as well as yours and become an inhabitant of the Fire: such is the evildoers' reward.' But his soul prompted him to kill his brother: he killed him and became one of the losers. God sent a raven to scratch up the ground and show him how to cover his brother's corpse and he said, 'Woe is me! Could I not have been like this raven and covered up my brother's body?' He became remorseful. On account of [his deed], We decreed to the Children of Israel that if anyone kills a person -unless in retribution for murder or spreading corruption in the land- it is as if he kills all mankind, while if any save a life it is as if he saves the lives of all mankind." - [ The Feast 5: 27-32]
I would love to explain what I got from it, but I fear restricting it's full picture with my small views.
